Wheel Fitment / Clearance Notes
Wheel Clearance will need to be confirmed prior to finalizing your order. As with all big brake kits, you will need to confirm the caliper will not make contact with the wheel. We strongly recommend using the printable template (found in the link below) to measure. 345mm rotors will typically require use of an 18" wheel.
