Endless Racing Big 4 Rear Performance Brake System for R33 Nissan Skyline GT-R

4POT caliper kit for rear only for full-scale use such as circuit use Big caliper for rear that maximizes the amazing stopping power. Demonstrate reliable stopping power by making the size larger than the conventional rear caliper. In combination with the 12POT or 6POT front caliper, it creates an ideal front-rear braking balance and realizes reliable braking by four wheels.

The caliper body is lightweight and highly rigid due to forged aluminum. It also has excellent heat resistance, so it maintains high performance even when used for a long time on circuits and windings.


  • Weight : 3486g
  • Size : 157mm x 79mm x 278.5mm
  • Compatible Rotor Diameter : φ355mm – φ370mm
  • Std Color of Kit : Blue Anodize
  • Std Compound for Kit : SSM / TR / MX72 / MX72PLUS
  • Corresponding Wheel Size : 17″

For racing, rally or street, Endless only uses the highest quality materials and design to achieve the best performance possible. These calipers will cope in the toughest of conditions without flexing or losing accuracy. Combine the calipers with RF650 Racing Super Fluid for optimum performance. Your pads will be applied and released with great precision and reliability.

Blue Anodized Finish

When raw aluminum reacts with the oxygen in the air, a hard surface film develops on aluminum which prevents further degradation. The process is called oxidation, and you can think of it like rust. The anodizing process leverages this natural phenomenon, and takes it a step further to produce an extremely hard protective layer of aluminum oxide. The result is a finish that is far more appropriate for racetrack use. Anodizing creates a uniform surface that is much more abrasion resistant than paint or powder coat.

“E-Slit” Double Shaving Effect

The long slit which draws gentle curves and the E slit which runs above the long slit are what make E-Slit Rotor impressive. The pad is constantly kept in optimal shape through the double shading effect demonstrated by the long slit, which gently carves the pad, and the E Slit, which gives strong brake force, providing further improvement of brake force. When the long slit on the rotor surface side disappears and the letter E floats up it is about time for replacement.

Also, even during the period of use, the brake rotor may be damaged due to aging deterioration such as rust and corrosion, so it is recommended to replace it at least once every two years.


  • Material : Steel with Special Carbon
  • 1-Piece Design
  • Slit Shape : E-Slit
  • Special Heat Treatment


  • The E-Slit rotor consists of the narrow curved slit incorporated with 4 smaller E-Slits. The smoother shaving of the pad by the long curved slit and the increased friction provided by the E-Slits maintain optimal brake pad condition at all times. The rotor material consists of a special carbon blend, an Endless original technology, facilitating stable mu-levels, decreasing heat cracks and extracting 100% of the brake pads performance. Slits are designed for optimal shaving.

Cost Effective, and More On So Many Levels

  • Endless Steel discs are more cost effective, and offer a wider range of performance options. Many drivers and racing teams prefer the feel and characteristics of Endless steel discs.

Special Heat Treatment Process

  • With prolonged hard driving, the rotor surface will expand and contract due to heat, causing fine cracks (heat cracks), and you will not be able to obtain appropriate friction. To prevent this, special heat treatment was performed in advance to stabilize the components of the rotor itself and significantly reduce heat cracks during hard driving. As a result, the life of the rotor has been extended, and it has become possible to use it for a long time with peace of mind.

Blue Rotor Hat Finish

  • The bell hat part is painted blue to aid in preventing corrosion resistance and also can be expected to have a dress-up effect.

About Bedding

Circuit-dedicated pads that emphasize high-temperature characteristics, in order to bring out the original performance, it is indispensable to perform the work called “bedding” in which heat is applied in advance before hard driving to make a hit.

Bedding is always done in the top categories SUPER GT, WRC and various races in Europe.

Before using semi-metal brake pads, proper bedding is required to stabilize high temperature performance and extend the life of the pads and rotors.

How to Bed

  • When driving on a circuit when a new product is installed, raise the rotor temperature to about 400 – 500° C while avoiding hard braking, and add atari. After that, if the temperature is lowered to 100° C or less by natural cooling, the process is completed.

Kit Contents

  • Endless Racing Calipers (2)
  • Brake Pad Set
  • Caliper Mounting Brackets (2)
  • Large Diameter Brake Rotors (2) – 370mm x 34mm
  • Stainless Brake Lines (2)


  • It may not be possible to bring out the original performance of the brake pads when bedding in the rain. Bedding should be done in fine weather as much as possible.
  • Compatible wheels vary depending on the wheel brand and size.
  • E-Slit rotor is adopted as standard for this product.
Items that are in stock in the US, either at Bulletproof’s warehouse or at a supplier’s warehouse, are generally delivered within 7-10 days. Special order items from overseas take considerably longer. As a courtesy Bulletproof offers delivery estimates to our customers which take into consideration manufacturer availability and shipping schedule. These estimates represent our best guess based on previous orders from the manufacturer and do not in any way imply a guaranteed delivery window. Many manufacturers work in a “just in time” inventory system and often take 2-20+ weeks to produce an item once an order is submitted. All deliverable items are then sent to our Japanese warehouse. Bulletproof ships a minimum of one full ocean freight container every month from Japan, oftentimes more than one a month. Ocean freight takes an average of 4 weeks. Typically it breaks down to one week in Japan for paperwork and customs, two weeks by boat and one week in US customs/clearance. Due to the wide number of variables between manufacturer and shipping schedules, delivery estimates are simply just that – estimates. We attempt to estimate conservatively and we usually deliver faster than our estimates suggest. It is not Bulletproof’s policy to guarantee delivery time of any special order item, this is impossible for us to do. By ordering you acknowledge that there is no required delivery ETA and an order may not be canceled or altered due to manufacturing or shipping delays, all ETA’s are provided as a best guess only. Please review the full Terms & Conditions.
