Girodisc A2-177 Rear Rotor FAQs:
Do these rotors require any special adapters or brackets? No adapters are needed. The Girodisc setup bolts directly to the factory hubs and uses the OEM Brembo rear calipers without modification.
What kind of weight savings can I expect? Compared to the stock one-piece cast rotors, these Girodisc units save roughly 2 lbs per side, improving suspension response and rear-end agility.
How do these perform during long sessions on track? The floating design and directional vanes keep rotor temperatures consistent, preventing fade during extended high-speed braking zones—especially useful for RS6 drivers pushing heavy cars hard.
Can I pair these with street-focused pads? Yes. They work seamlessly with OEM-type street pads or more aggressive compounds like Ferodo DS2500 or Pagid RSL for dual-use setups.
