Girodisc Acura NSX Rear Replacement Rings

Refresh your Acura NSX’s braking performance with Girodisc 350mm rear replacement rings. Built for precision and endurance, these high-carbon iron rings are direct replacements for Girodisc two-piece rotors, maintaining your NSX’s balance of power, control, and stopping confidence.
Vehicle Fitment
Compatible with:
• 2017–2022 Acura NSX (NC1)

Precision-Built for Consistent Braking
Each Girodisc replacement ring is cast from a proprietary high-carbon iron alloy and machined to exacting tolerances in the USA. The rotor’s directional curved vane design acts as a centrifugal air pump, drawing cooling air through the rotor to reduce heat buildup and prevent brake fade. Whether you’re carving backroads or pushing your NSX to its limits on track, Girodisc ensures reliable braking with smooth pedal feedback and long-term durability.

Girodisc D2-174 Replacement Ring FAQs
Will these fit factory NSX brake setups? No. These are designed for use with Girodisc two-piece rotor systems or equivalent aftermarket aluminum hats.
Do these include new hardware? Yes. Each set includes new floating hardware—pins, bolts, and washers—for a complete, ready-to-install replacement.
Are these compatible with both NSX generations? Yes. They fit directly on second-gen (NC1) NSX models and first-gen NSX cars equipped with Girodisc 350mm rear brake kits.
What makes Girodisc rotors better than OEM? Girodisc rotors are lighter, cooler-running, and fully serviceable. The two-piece design allows you to replace just the iron rings instead of the entire rotor assembly, saving cost over time.
