Wilwood 140-12508 Details

Kits in this competition group are configured for use in production category road racing that allow brake upgrades, but limit modifications to four-piston calipers and 12.20" rotors. BSL4R/ST calipers use Thermlock pistons to resist fade and extend service life by reducing the heat transfer into the caliper from the pads. GT series directional vane rotors provide high cooling efficiency and durability mounted to the hubs with forged aluminum GT hats. Kits also include high temperature race compound pads, stainless steel flexlines, and premium grade hardware for installation in 16" and larger wheels.
