GiroDisc Rear Rotors for R35 Nissan GT-R

GiroDisc’s Rear Rotors for R35 Nissan GT-R models fit every year of the car, from the first CBA chassis to the final 2025 builds, because GiroDisc makes a single 380mm rear rotor for the whole R35 run. GiroDisc puts each rotor at about 18.8 lb, a saving in unsprung and rotating mass that shows up as quicker suspension response. The ring is GiroDisc’s own iron, poured in the USA and machined start to finish in Bellingham, Washington, then floated on 10 cadmium-plated drive pins around a hat of US-sourced 6061-T6 aluminum. With either GiroDisc front rotor, it completes a four-corner set for an owner who would rather refine the factory brakes than replace them.

Design and Performance

• As a direct replacement for the factory rear disc, it bolts on and works with the original rear calipers with no modification, keeping the front-to-rear bias and ABS behavior Nissan engineered. Ten drive pins carry the braking load while letting the ring float, and anti-noise spring washers remove the cold rattle floating rotors can make. When the iron wears, only the ring is replaced.

Features

• GiroDisc Rear Rotors for R35 cars of every year, at the factory 380mm diameter
• Approximately 18.8 lb per rotor, by GiroDisc figure
• Hat machined from US-sourced 6061-T6 aluminum
• GiroDisc iron ring, poured in the USA and machined in-house
• Curved vanes that move cooling air from the hub to the rim
• 10 cadmium-plated alloy steel drive pins
• Slotted face that keeps the pad surface clean
• Left and right handed, labeled for position

What’s Included

• Rear rotor assemblies (L/R)

Applications

• Nissan GT-R: R35 | 2007-2025 | 3.8L VR38DETT

Notes

• The front rotors are year-specific: 2007-2011 cars take the GiroDisc 380mm front rotors and 2012 and later cars take the GiroDisc 390mm front rotors
• Worn rings are replaced with the GiroDisc rear replacement rings, which bolt to these hats
• The cap screws can look loose by design and are never tightened beyond 60 in-lb (7 Nm)
• Stock photography may not depict the actual product

Frequently Asked Questions

• Do the GiroDisc Rear Rotors for R35 fit every GT-R year? Yes. The GiroDisc Rear Rotors for R35 fit every model year of the Nissan GT-R, from the early CBA cars through the final 2025 production. Only the front rotors change with the year: 2007 to 2011 cars take the 380mm front rotor A1-249, and 2012 and later cars take the 390mm front rotor A1-232.
• How much do the GiroDisc rear rotors weigh? GiroDisc gives the rear rotor weight as approximately 18.8 lb per rotor. The saving comes from replacing a solid iron center section with a 6061-T6 aluminum hat, and because the rotors spin and sit below the springs, the lighter assembly reduces both rotating and unsprung mass at the rear axle.
• Will the rear rotors work with the factory calipers? Yes. GiroDisc designs the rear rotor as a direct replacement for the factory disc, so it bolts to the car and works with the original rear calipers and pads with no modifications. Factory brake bias and ABS efficiency are kept, unlike with a big brake kit.
• Do the rear rotors need to be bedded in? Yes. GiroDisc bedding starts with the rotors, preferably on previously used pads, using light to moderate stops that bring the surface to about 700 to 800 F, then a cool down to near ambient without dragging the brakes. New pads are then bedded to their maker instructions.
• What happens when the rings of the Rear Rotors for R35 wear out? Only the rings are replaced. GiroDisc D2-232 rear replacement rings come in pairs with new hardware and bolt to the existing hats of the Rear Rotors for R35. The minimum thickness is marked on the hat and on the outer edge of the ring, and the rings are changed once they reach it.

About GiroDisc

GiroDisc designs, manufactures, and sells 2-piece, fully floating brake rotors for a wide range of performance vehicles. Every major component, including the hats, rotor rings, and drive pins, is manufactured in-house at their facility in Bellingham, Washington, from domestically sourced materials. GiroDisc rotors use a proprietary high-carbon iron ring formulated for superior metallurgy and thermal performance, paired with reusable machined-aluminum hats that reduce the long-term cost of maintaining a high-performance brake system. The 2-piece floating design sheds unsprung and rotating mass while remaining street-friendly, delivering race-proven braking for track and street use alike.
