Race-Bred Design, Everyday Driveability
The Girodisc system replaces the factory one-piece rotor with a floating two-piece assembly designed for durability and heat efficiency. The rotor hats are CNC-machined from 6061-T6 aircraft-grade aluminum and anodized for corrosion resistance. The cast-iron rings feature Girodisc’s proprietary alloy, cast and machined in-house in the USA. A dimpled and slotted surface pattern promotes consistent pad contact, gas evacuation, and cooling—ideal for high-performance driving while remaining quiet enough for daily use.

Girodisc A2-022DS Rear Rotor FAQs:
What’s the benefit of dimpled and slotted rotors? The surface design increases initial pad bite, expels gases and debris, and maintains optimal friction under repeated heavy braking—perfect for spirited driving or track use.
Are these rotors direct-fit replacements? Yes. The A2-022DS bolts directly to the factory hubs and uses the stock calipers and brake lines with no modifications required.
Will they make noise like drilled rotors? No. Girodisc’s dimpled and slotted pattern provides improved performance without the cracking or whistling often associated with cross-drilled rotors.
Can they handle track temperatures? Absolutely. The two-piece floating design and vented construction allow the rotors to expand evenly under extreme heat, maintaining balance and reducing fade lap after lap.
Enhance your Mercedes’ braking confidence and consistency with Girodisc 330mm dimpled and slotted rear rotors—precision-engineered for performance that lasts.
