Fitment & Compatibility

Use this five-hole Scion front hat only with the conversion that specifies its 2.17-inch center and 0.710-inch offset. The hub-side 5 x 3.93-inch flange is separate from the twelve-on-8.75-inch rotor attachment. Confirm the correct rotor, bracket and mounting hardware for that assembly; other Scion hats use different registers and flange layouts.
