QUESTIONS RIDERS ASK

Is this price for one rotor or a pair?
One rotor. BrakeTech sells the left and right separately (each has its own part number), so a front pair is one Left plus one Right from this listing.

Why the 6mm Race-Spec over the 5mm?
Thickness is thermal capacity. BrakeTech's 6mm blade carries more mass at the friction ring, which manages the heat of sustained, aggressive braking and keeps performance consistent from the start of a session to the end.

Spoke mount or hub mount — which do I have?
They're two different wheel mounting styles and they don't interchange. If you're not sure which your front wheel takes, email us a photo of the wheel and rotor and we'll confirm before you order.

When will my rotor ship?
These are on backorder at BrakeTech with no published ETA. Ordering reserves yours — we relay it to BrakeTech right away and email tracking as soon as it ships.
