Description
Offsets the original caliper to increase rotor diameter from 258mm to 305mm. Improves handbrake effectiveness for easier handbrake turns with less effort. Helps adjust front-to-rear brake balance when larger front calipers are installed and provides a brake size that suits large wheels visually. The 5H/4H multi-hole design also supports 4-hole vehicles, starting with shipments from August 2026.
- Installation requires modification of the backing plate and related work. A black-painted rotor bell is also available.
- Specifications and prices may change, and production or sales may be discontinued without notice.
