PRODUCT FEATURE: Bulletproof Automotive / GT-RR Exclusive “Frozen Carbon” Wheels

Here at GT-RR / Bulletproof Automotive, we love carbon fiber! From our full carbon fiber-bodied Overtake demo car and customer builds, to our carbon fiber interior conversion services, we are obsessed with anything and everything carbon! Over the years, we’ve worked to find any creative way to use carbon fiber we could find. During our experimentation, we developed our exclusive “Frozen Carbon” wheels. Up until now, our Frozen Carbon wheels have been one of our lesser known offerings, with only a very select few sets existing. However, in the last year or so, we’ve seen renewed interest from customers looking to do something truly unique and set their cars apart.

It’s all in the details…

The Frozen Carbon process begins with an authentic wheel from any high-quality manufacturer (Rays, Advan, Work, ADV1, HRE etc.), which we then permanently add accents of real carbon fiber, and finally finish with colors inspired by BMW’s famous “Frozen” series of limited edition paint colors. The end result is a truly unique re-imagining of the original wheel, with details that true connoisseurs can appreciate. Frozen Carbon is available for virtually any wheel, and in virtually any color (we recommend satin or matte finishes).

GT-RR Custom Carbon Fiber Converted Interior Parts for R35 Nissan GT-R

Back in 2010 we had this idea to remix the GT-R shift knob with carbon fiber replacing plastic, and more exotic upholstery like Alcantara, high-end leathers and custom stitching. We were the first in the world to do it. Since then we’ve done quite a few crazy interiors, a ton of custom carbon fiber parts (50+ various pieces throughout the car), and a lot of other wild, one-off stuff. They are slow to make, all hand made and since they are custom they can’t be kept in stock. Various other hand made carbon fiber interior pieces however we do try to keep in stock for special projects.

For our carbon fiber interior pieces, we take factory Nissan parts and convert the outer surfaces to real carbon fiber. The process is much different, and much more OEM looking than the tape-on carbon pieces typically sold as it maintains the stock thickness of the parts, thus retaining the OEM feel of the buttons and switches on the steering wheel switch plate, mirror control and triple switch/hazard panels, for example. This service is offered for virtually any part on the GT-R, with the most often converted pieces being the dash vents, steering wheel switch plate and door handles.

We wanted to feature a small gallery of several of the interiors we’ve either completed in-house or for which we’ve supplied parts.



GT-RR Visits Tokyo Auto Salon 2017 (Part 2)

In our last post, we gave a partial recap of some of the greatest new GT-R parts displayed at Tokyo Auto Salon 2017. For this post, we’re going to continue our coverage with some of our other “must see” picks for the new year!


TAS 2017 is considered by many as the “return of classic Top Secret;” the reason for this comes from the debut of their “VR32 Skyline GT-R.” The VR32 is an incredible mash-up of two of Nissan’s most popular sports cars, the R32 Skyline GT-R and the current R35 GT-R. With the entire driveline transplanted and retrofitted from an R35 into a heavily modified R32 chassis. Top Secret even went as far as fitting the interior and the entire carbon-composite front core support from an R35!

Top Secret Skyline VR32 GT-R:


Top Secret also had several R35 GT-Rs on display featuring a large collection of both their existing and newly debuted parts. They even had a brand new 2017 GT-R on display, which featured their first full replacement side skirt set for the R35 GT-R. Their silver WTAC-veteran silver circuit demo car was also on display, as well as several customer R35s, including the fully-tuned, custom red painted car pictured.

New Top Secret Parts for 2017:



For 2017, Aimgain again drew inspiration from the GT-R Nismo and GT3 race car when designing their revised GT widebody kit. Aimgain’s GT Line of aero parts are meant to transform the look of traditional sports cars by adding a unique “wide and low” appearance.

The 2017 Version kit adds some of Nissan’s newest design elements includes a GT3 / Nismo-inspired front bumper, front grille, and front lip spoiler. The remainder of the kit adds elements of Aimgain’s “wide and low” styling, including their side under spoilers (side skirts), rear under spoiler and diffuser set, and Aimgain’s unique wide body front fenders (50mm wider), and rear fenders(80mm wider).

Aimgain GT 2017 Version Widebody Kit:


The bolt-on over fender craze has finally made its way to the classic R32 GT-R with the newest kit from Pandem (Rocket Bunny). Featuring massive front and rear over fenders, the kit adds some serious girth to the R32 chassis! Also included in the kit is a front lip spoiler and side skirt set featuring clean and simple lines. The primer grey demo car on display at TAS also featured the all-carbon fiber version of the optional Duck Tail Rear Wing, as well as a set of custom 6666 Wheels by Enkei, and a Greddy exhaust.

Widebody Kit for R32 Skyline GT-R:


With the release of the facelifted 2017 GT-R, all the popular Japanese manufacturers jumped on the opportunity to produce new parts for the massively updated exterior. Rowen was no exception, keeping to their annual tradition of new aero parts for the R35. For 2017, rather than immediately jumping to creating an aggressive or wild-looking kit, consisting of replacement bumpers and the like, the designers at Rowen opted for a simpler, add-on lip kit to compliment the new GT-R’s already muscular aero. The kit consists of a front lip spoiler, side skirts, rear under spoiler extensions and a brand new rear wing and trunk spoiler combination. The black 2017 demo car also featured Rowen’s line of titanium exhaust parts.

Crystal Eye is known in Japan for their impressive LED lamp upgrades for various cars. At Tokyo Auto Salon 2017, they released their next generation of upgraded tail lamps for R35 Nissan GT-R. Crystal Eye’s Double Fiber Ring LED Tail Lamps feature a unique “finned” design with LED illuminated rings, turn signals and reverse lamps. The tail lamps are available with either classic red lens, or smoked clear lens for those that like the “blacked out” look.

Customer Install: Back-To-Back 2017 GT-R Exhaust Installations at GT-RR!

Happy Holidays!

In a funny coincidence late last week, we happen to have two local customers both with 2017 GT-Rs schedule installation of aftermarket exhausts for their new toys on the same day.

The first car is a black 2017 with the luxurious optional Amber Red interior. The owner also had a modified 2014 GT-R, so upgrading the exhaust to a 94mm Greddy Supreme Ti on his brand new car (paper license plates and all) was nothing new for him.

Greddy Supreme-TI 94mm Titanium 

Greddy’s Supreme-Ti is a full exhaust system (midpipe and rear section / catback) produced completely from high-quality titanium, with a 94mm main pipe.

Next came a good customer of ours who previously brought in his blue 2017 for a set of our exclusive Bulletproof Automotive Gold TE37 Ultra Wheels. As a connoisseur of premium tuning parts, nothing but the Overtake Saikou 100mm valved exhaust would do for him.

Overtake 100-v Saikou Exhaust

The Overtake exhaust is constructed of full STTI titanium for the maximum in weight savings, with the addition of an electronic remote-controlled valve system to allow the driver to choose between two “personalities;” valves-closed, quieter mode for around town driving, and a valves-open, louder mode for maximum flow and sound.

For more information on either of these exhausts, or if you’re ready to upgrade your 2017 GT-R, feel free to contact us: or +1 213.745.6954

Customer Install: Overtake Carbon Accents on Brian’s Super Silver R35

Our friend and local customer Brian dropped by yesterday to have a few Overtake parts installed on his Super Silver GT-R.

He picked up a collection of Overtake’s high-quality dry carbon fiber exterior accessories, including:

SEMA 2016 Debut: GT-RR x Fury Automotive Varis Kamikaze-R Super Sonic North American Demo Car

Earlier this year, our wholesale customer and friend Fury Automotive from New York came to us looking to build a World-Class GT-R for SEMA 2016. Having experience creating quite a few popular SEMA cars in the past, the guys at Fury knew that we could help them achieve their goal. Almost immediately following the release at Tokyo Auto Salon 2016, the guys at Fury fell for the Kamikaze-R Version 2 “Super Sonic” aero kit from Varis.

As the North American importer and distributor of Varis parts, we worked with them to source the first production Kamikaze-R 2 Super Sonic kit for Fury’s special build. The kit features front and rear wide fenders, wide side skirts, and vented front and rear bumpers. Fury also opted for Varis’ Version 2 vented carbon fiber hood, and their new swan-neck carbon fiber GT Wing which includes a special trunk mounting base / reinforcement plate to help support the high amount of downforce supplied by the large, 1800mm wing plane.

[envira-gallery id=”1006″]

With the desire for a very unique, world-class SEMA build, Fury consulted with us for one of our popular custom interiors. Real carbon fiber and personalized Recaro Japan seats give it a premium look and feel.

Not wanting to have a GT-R that only looked the part, the guys at Fury added an impressive list of performance parts, from power to suspension, including JCR’s complete carbon fiber intake manifold, as well as our gold big throttle body kit, a collaboration with AT Power.

For suspension, the guys at Fury opted for Aragosta’s Type-SA PnP coilover kit, a full coilover that retains the OEM damper setting switch’s functionality. They also added on Aragosta’s front air cup lifter system to help prevent any damage to the beautiful Varis carbon front racing diffuser.

Overtake x Sachs 3-way Suspension Installed on a Nismo GT-R!

Our good friend and local customer, Peter recently brought in his Nismo GT-R for some small carbon fiber upgrades – an Overtake Dry Carbon Roof, Overtake Carbon Fender Vents and Emblems, and some Overtake Embems to cap it all off. Little did we know that these mods would kick start his shared love for Overtake’s premium quality parts! After a suspension failure on his other GT-R, a Black Edition, he came to us for some suggestions, and we collaborated with him on a plan to not only upgrade his B.E., but also further improve the handling of his Nismo. Since Peter is a professional race driver, instructor and overall track junkie, the Overtake x Sachs Super GT race-car derived suspension was the perfect option to take his Nismo to the next level.

The Overtake suspension is produced by Sachs in Germany (an OEM and highly respected race team supplier), and is directly related to [derived from] their offering for the Super GT Nismo race vehicles. Overtake offers their coilovers in several configurations, including 2-way and 3-way, and as an experienced race driver, Peter opted for the 3-way specification. (For reference, our SPL demo car also features the 3-way version, and our other client’s car – with the complete Overtake carbon fiber exterior, and custom interior – features the 2-way version.)


Overtake Suspension Installed on Peter's GT-R Nismo - COMPARISON WITH OEM

The Overtake pieces are a direct replacement for the OEM (obviously, as proper motorsports-grade dampers with multiple adjustments, the Nissan electronics are not retained). The dampers are produced in full aluminum, which we decided to put to the test against the OEM steel shock bodies when it came to weight:

As he’s a professional racing driver, Peter takes his Nismo to the track frequently; here’s a couple quick shots of the first suspension shakedown at Buttonwillow:

At HKS USA’s First Annual Speed Ring Event this past weekend, Peter won the Limited AWD Class Title with a time of 1’48”! He advised that his Overtake 3-Way suspension, paired with his new Michelin Pilot Sport Cup 2 tires were the major contributing factors to his win. He felt the car definitely had the capability to go faster, but was limited by the factory cooling systems’ capabilities.

Custom Overtake Dry Carbon Racing Hood Project

Overtake Japan Logo
Not long ago we had a longtime friend/client from overseas approach us with a very special request for his GT-R. The client had ordered an Overtake dry carbon racing hood, which in and of itself is gorgeous as is; however he wanted something a bit more unique … something that would really take his build to the next level. He didn’t really know what but he knew he wanted something “special”. Knowing that we were well experienced in custom design and production of specialized parts, our client instilled his trust in us to come up with an amazing design idea and that’s just what we did.


After being tasked to create a special hood, our carbon composites and special projects engineers went to work. We spent countless hours analyzing, dissecting, and rebuilding a few designs for the hood until we finally came up with something that tied together an old concept with a more modern design and execution.

We had the idea of making a display window out of Lexan in the center of the hood. We could have just cut a hole in the center of the hood and laid a piece of Plexiglas in the center of it, but that wasn’t good enough for us so we decided to build upon that idea. Instead of having a flat surface with a hole filled with some see-through Plexiglas, our engineers created an entire functional cowl from scratch to house the piece of clear Lexan. The cowl was designed to also provide extra ventilation by having small air outlet ducts which sit behind the raised portion of cowl.

For testing and fitment purposes, we installed the hood on our full Overtake dry carbon shop GT-R. You can see the gorgeous Amuse x Overtake SAIKOU Titanium Surge Tank sitting right in the middle of the see-through Lexan.

All in all, we’re happy with the way it turned out…

INTRODUCING: brand_RR Front Switchback Clear LED Winker Lights for NISMO GT-R

Way back in 2011, we released the world’s first Front Switchback LED Turn Signals (winkers) for the GT-R. “Switchback” is a bit of an ambiguous term for most people, but the gist is that when the headlights or parking lamps are activated, the marker illuminates white. As soon as the turn signal (or hazard) is activated, the lamp immediately switches from white illumination to amber flashing. When the turn signal is deactivated, the lamp re-illuminates to white.  The result is a match to the white light output of the headlamps at night.

As the Nismo GT-R (as well as the EDM / JDM Track Edition by Nismo) features wider front fenders, we knew a Nismo-specific version of our Switchback Winkers was necessary. In designing these lights, we actually ended up creating our own custom, in-house produced clear lens that offers better light diffusion.

All brand_RR Front Clear Switchback Winkers begin life as OEM Nissan Japanese-spec clear winker lamps, and are then modified with custom-made clear lenses, a custom-spec’d LED array, as well as a specially CAD-engineered internal reflector for even light diffusion and an OEM look.

As far as installation, it’s simple; as they utilize the standard marker lamp’s socket, with only one additional wire per lamp that needs to be spliced. (A full-color, detailed installation manual is provided.)

Note – These have been tested with US Specification GT-Rs, they may respond differently with Japanese Spec GT-Rs.

Pricing is $475.00 – to order, feel free to contact us – +1 213.745.6954 / or to purchase on our website:

Behind The Scenes – Nordring

This is going to be the first of perhaps many of our behind the scenes posts of Japan’s tuning shops (hopefully you enjoy them). Over the past 16 years one of our greatest joys has been playing an early role in introducing Japan’s tuning shops to the world. After nearly 100 trips to Japan over those years, and all these years sharing this crazy passion we have for GT-Rs I’ve gotten to know many of the shops closely and I’ve come across some great stories and background which fellow GT-R owners might enjoy. With internet content typically operating in bite-size pieces, here’s a bit more than usual. I hope it humanizes and makes some of these legendary shops understood and appreciated in new ways. Many of these shops have an “oversized” image but are often under 10 employees and are built around the same passion that unites us here in the community.

Suzuki-san Behind the Scenes of Nordring Japan

I’ll start with Nordring and if you guys like where I take this, I have a lot of original content, stories and history with dozens of other small shops ranging from MCR to JUN to HKS Technical factory to Varis to Top Secret. Each one deserves its own spotlight but I’ll start here with a small shop run by Toshio Suzuki.
Suzuki-san, prior to opening Nordring, was at first a Formula 1 driver and then later was Nissan’s test driver and was responsible for the initial R35 iconic lap time at the Nurburgring that put the GT-R on the global stage and put all supercars on notice. His role was primarily to provide feedback to Mizuno san who at that time was head of the R35 GT-R program and prior was responsible for the R34 GT-R. Shown in the photos here is the original R35 GT-R test mule packaged into a CPV35 Skyline Coupe. That original test car resides at Nordring’s office and represents some of Suzuki-san’s iconic history at Nissan shaping the GT-R and his close ties to his colleague Mizuno-san.

Suzuki-san’s talents as a race car driver, test driver and chassis/suspension expert are unquestioned. As his age increased, he retired from racing and opened up Nordring which is named after the famous race track that he conquered time and time again in Germany. Knickknacks from the Nurburgring are all over his office, even the coffee set we drank from is Nurburgring branded.

Nordring’s start coincides during Suzuki-san’s friend Mizuno-san’s rule over the GT-R world. For those of us in the GT-R community that were involved when the R35 first came out, Mizuno-san and Nissan had a FIRM stance on not modifying the car. You could feel it when reading the manual and seeing a do not modify cartoon image, and you could equally feel it during the times I was at Fuji Speedway during the early R35 era Nismo Festivals when there was a ban on all modified R35 GT-R’s on display at the event. Unlike overseas, Nissan dealers in Japan are under tighter corporate control and there was a culture of fear that if you modified your GT-R Nissan would blacklist you. There was however a single company that Nissan recognized under warranty and at Nismo Festival, that company was Nordring and Nordring alone.

For all of the time and support Suzuki-san had given to Nissan, Nissan in turn supported Suzuki-san and trusted him with his upgrades for the GT-R under Nissan warranty and with dealer install. During these early years of Nordring, even despite our relationship with them, I had trouble ordering the parts directly for overseas GT-R clients who depended on our company to bridge the cultural and physical divide. For months and then years, Nordring would politely tell me to check back later since they were waiting on Nissan’s approval to sell overseas. Since Nissan had a hand in Nordring’s parts sales, the corporate giant also had a hand on distribution and had to personally approve any overseas sales route. During that time, getting Nordring parts was tricky and although we had our ways, it was not until Nissan loosened corporate dominance over Japanese tuning that Nordring could operate more freely without Nissan’s hand. Nissan’s corporate position about the aftermarket, warranties, and tuning in Japan changed when Tamura san replaced Mizuno san for the GT-R program by the way. This is a whole different story in itself, and a great one…but for another time. Anyway, in our opinion, Nordring did not need Nissan’s support to restrict the competition and in fact Nordring will always hold a number of key advantages, mostly due to Suzuki-san’s brilliance at circuit setup and knowledge.

Behind the Scenes of Nordring Japan by
The Nordring brand and what it means currently in Japan:
Nordring is a small shop, that when you visit feels more like a hobby of a pro driver where he and his buddies can meet. The clients that visit are fiercely loyal and are almost always there for one defining thing – Suzuki-san’s expertise in setting up their car to handle amazing on the street and circuit. Suzuki-san was the trusted source for Mizuno and his team with the R35 and he carries that torch with a personal touch for his local clientele who love going to the circuit. Suzuki-san’s suspension of choice is the same as used on Mizuno-san’s R34 GT-R Z-Tune project and on Nismo’s Super GT cars, a high end coilover produced in limited supply by Japan’s Sachs Motorsports division. Although this suspension is favored by Suzuki-san and his clients, after Mizuno san left Nissan the later special Nismo projects moved from the special Sachs units to Ohlins dampers. Debate still rages on in Japan by purists over which rules supreme but Nordring clients go crazy for the Sachs, one story even has an N-Attack user removing his N-Attack special Ohlins to switch to the special Sachs 3 way coilovers. Aside from coilovers, Suzuki-san has been favoring Drexler differentials and has been utilizing the suspension and differentials along with his special alignment settings for many of the top drivers and GT-R owners in Japan. One theme with Suzuki-san is that he doesn’t compromise, everything is the best, price be dammed. Another theme is that his focus is on balanced tuning and vehicle dynamics, not simply on big power.

An interesting note is how Nordring is perceived inside Japan versus outside. Outside Japan, the secret sauce of Suzuki-san personally setting up a car with those special dampers and diffs is not really a possibility since he’s the one doing the work locally. An entirely different Nordring exists outside of Japan, one that involves their dry carbon parts. The story goes at that the owner of Challenge is a GT-R enthusiast and he developed a few GT-R parts for fun but had no outlet to sell them. Challenge as you probably know, makes the rear diffuser for all R35’s and makes the Nismo GT-R body panels, amongst other things. In fact, their big business is making Shinkansen/Bullet Train nose cones and a variety of other more lucrative projects. The aftermarket is not their focus (although I’ve personally been a user of Challenge made dry carbon parts since 2004 on our S2000 and they do dabble in aftermarket projects time to time). Anyway, Challenge has bigger tasks than to market a lineup of aftermarket GT-R parts and they found a partner in Suzuki-san to introduce these items through Nordring. Since Suzuki-san is an expert at suspensions, this was clearly no conflict of interest and in-fact rounded out the Nordring lineup well. For those Nordring clients overseas, odds are your Nordring experience is with the Challenge made Nordring dry carbon parts which are as expensive as they are beautifully constructed.

Going into the future, it is hard to say where Nordring is headed. I get the feeling from Suzuki-san and the shared friends we have that he is perfectly content going to the race track, hanging out with GT-R owners and setting up cars. It feels as much hobby as it does business and there is no urgency to grow big. He has already left his mark and now he seems to be enjoying himself. The international clientele can now freely get Nordring parts through Bulletproof (shameless plug) and through other authorized dealers, and although there does not seem to be many new parts on the horizon, the current parts are all timeless and well thought out.
We’ll share more photos and be happy to chat more on this. We certainly don’t know everything, but this is a rough and unofficial history from our experiences being a Nordring dealer and friend since the origin of the brand.
