Fitment notes

Most 17" wheels will clear these calipers. Always confirm spoke clearance with your specific wheel design.

For dedicated track setups, a more aggressive rear pad compound is recommended to fine tune balance.

The four longer bolts pictured are attached to the factory caliper carrier. Remove the OEM carrier and install the supplied carrier in its place.
