Girodisc Rear Brake Rotors – Nissan GT-R

The Girodisc A2-232 Rear Rotor Kit is a direct replacement for the OEM rear rotors on the Nissan GT-R. Designed to deliver race-proven performance with factory fitment, these lightweight two-piece rotors enhance cooling efficiency, reduce unsprung weight, and maintain perfect compatibility with stock calipers and ABS.
Lightweight Performance. Race-Ready Engineering.
Each Girodisc rotor combines a precision-machined 6061-T6 aluminum hat with a proprietary cast-iron ring, both sourced and built in the USA. The curved vane internal geometry acts as a centrifugal air pump, forcing cooling air through the disc to reduce temperatures and prevent fade under aggressive driving. The floating mount system allows the rotor ring to expand naturally under heat without warping or coning, maintaining consistent pedal feel and braking balance.

Girodisc A2-232 Rear Rotors – Nissan GT-R FAQs
Do these rotors fit the stock calipers? Yes. The A2-232 rotors bolt directly to OEM calipers and retain factory brake balance and ABS performance.
What’s the benefit of a floating two-piece design? The floating mount allows for thermal expansion and self-centering, improving braking consistency and minimizing stress that leads to rotor cracking or distortion.
Are replacement rings available? Yes. Girodisc offers replacement rings that allow you to reuse the aluminum hats and hardware for cost-effective long-term maintenance.
Do these rotors make noise? No. Anti-noise spring washers eliminate rattle when cold while preserving the benefits of a true floating design under heat.
Are these rotors lighter than OEM? Yes. The aluminum hat significantly reduces unsprung and rotational mass, improving acceleration, handling, and ride quality.
Are they sold individually or as a set? The Girodisc A2-232 rotors are sold as a pair for the rear axle.
