This is a 4-piston rally competition front brake system made by AP Racing for STI. They are Group N VO homologated for GDB and GRB/GVB (N12 and newer). Available as a gravel or tarmac system. Gravel system will fit under 15 x 7" rally wheels (please confirm with your wheel manufacturer). Tarmac system uses larger disc size with extension bracket for caliper. 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.
