Q: How does the floating rotor design help on track?

PFC’s full-floating Direct Drive attachment lets the disc expand and contract radially and axially without being constrained by the hub. That helps eliminate rotor warping while cutting drag, and it kills thermal judder, the vibration and pulsation you feel through a warped rotor. It also runs silent and rattle-free, which two-piece designs usually cannot claim. On a heavy car generating big heat, that stability keeps the pedal consistent.
