Mixing Fox and SN95 brake kits? Call us first.
If you are combining an SN95 (1994-2004) kit with a Fox (1979-1993) kit, or a Fox kit with an SN95 kit, please call us at (888) 378-8830 before ordering so we can run the calculations to make sure the kits will work together. If needed, we can ask Wilwood to do a no-cost caliper substitution to get the brake bias correct.
Forged XRS4R rear disc kits provide the ultimate Big Brake solution for popular muscle car rear axles that require a parking brake. XRS4R four piston calipers, 13" or 14" two-piece rotors, and high performance BP-10 compound pads provide optimized and balanced braking to compliment front big brake upgrades on all types of custom, show and high performance street machines. The neatly hidden internal shoe system provides a clean installation with superior static holding power for parking. Optional caliper finishes and rotor designs allow builders to personalize the style and performance for every application.
