STI/AP Rear Brake Kit

This is a 4-piston rally competition rear brake system made by AP Racing for STI. They are Group N VO homologated for GDB and GRB/GVB (N12 and newer). Rear kit is used for both gravel and tarmac applications and will fit under a 15 x 7" gravel rally wheel. This system is intended to be used with a hydraulic handbrake and eliminates the mechanical handbrake components. Modification to the rear uprights on MY08+ applications is required for fitment reasons. We can also supply lower cost non-homologated versions of these kits for competitors not needing to meet specific homologation requirements. Non-homologated versions use components that are not STI branded. Kits include calipers, caliper brackets, 2-pc floating discs with J-hook slotting, and brake bleeding tools. An optional disc cover is available to protect against stones.
