Girodisc D2-007 Subaru WRX STI Rear Replacement Ring FAQs
Do these fit factory WRX rotors? No. These are designed exclusively for Girodisc two-piece rear rotor systems and will not fit OEM one-piece rotors.
Will they clear OEM Brembo calipers? Yes. They are built to factory dimensions and work perfectly with the stock STI Brembo rear calipers.
Are these recommended for track use? Absolutely. Girodisc’s floating design and high-carbon alloy manage heat efficiently, preventing warping and fade during extended track sessions.
How often should I replace the rings? Replace when the rotor reaches minimum thickness or shows visible cracking or heat checking from repeated heat cycles.
