Details

This kit is configured for dedicated road racing on all 2005-2014 Mustangs. Four piston, nickel finish Quick-Silver FSL4R/ST calipers, with Thermlock® pistons and internal knock-back damping springs, are volume matched for system compatibility with either a factory power brake booster and master cylinder, or a manual balance bar style pedal with appropriately sized master cylinders. The kit includes two-piece 12.19” diameter Spec 37 alloy GT series directional vane rotors to comply with SCCA American Sedan rules, cross-overs into the NASA pony car categories, or any other sanction racing with 16” or 17” wheels. Unsprung and rotating weight are minimized by mounting the rotors to the OE hubs with forged aluminum hats. Each kit includes high-temp Wilwood race compound pads, machined billet radial mount caliper brackets, stainless steel braided flexlines, and all premium grade hardware.
