W4A Big Brake Front Brake Kit (Race)

W4AR/ST four piston radial mount calipers are coupled with the high cooling capacity of 14.00” SV-GT staggered directional vane rotors to provide the ultimate brake package for unrestricted road race competition. Thermlock pistons in the calipers resist fade and extend service life by reducing the heat transfer from the pads, caliper body, fluid, and seals. Rotors mount to the hubs with forged aluminum hats and radial mount brackets secure the caliper to the spindle in the OE location without modification. Kits also include high temperature, high friction race compound pads and all premium grade fasteners.
