Girodisc Acura NSX Rear Rotors
Bring world-class braking performance to your Acura NSX with Girodisc’s lightweight two-piece rear rotors. Designed as a direct OEM replacement, these rotors reduce unsprung weight, improve cooling, and deliver consistent pedal feedback for the hybrid supercar’s advanced braking system.
Engineered for Precision and Performance
The Girodisc system bolts directly to the NSX’s factory calipers and hubs—no modifications required. Each rotor is built around a CNC-machined 6061-T6 aluminum hat paired with Girodisc’s proprietary high-carbon cast iron friction rings. This floating two-piece construction allows for thermal expansion without warping, ensuring smooth, consistent braking whether you’re carving through mountain roads or attacking apexes at the track.

Girodisc A2-174 Rear Rotor FAQs:
Is this rotor setup compatible with the NSX’s hybrid regenerative braking system? Yes. Girodisc rotors integrate perfectly with the NSX’s factory electronics and regenerative braking calibration—no software or sensor changes needed.
How much lighter are these than stock rotors? Each Girodisc rotor saves several pounds over the factory cast units, reducing unsprung weight and improving suspension response.
Can I use factory brake pads with these rotors? Absolutely. Girodisc rotors are fully compatible with OEM pad shapes, or you can upgrade to performance compounds for track use.
What difference will I notice on track? Expect more consistent braking during long sessions, improved modulation, and reduced fade under high-temperature conditions thanks to Girodisc’s curved vane cooling design.
