Wilwood Product Release

Quick-Silver/ST Road Race Brake Kits for the SCCA and NASA Racing Series


Wilwood’s Pony Car road race kits now feature the superior performance and durability of our Superlite 4R/ST Quick-Silver calipers. Quick-Silver/ST calipers have become the dominant force in SCCA’s TA-2 series and other extreme-duty racing categories as well. The calipers feature a rigid forged aluminum radial mount body, a long-wearing nickel plate finish, Thermlock® pistons and internal piston-damping springs.

In addition to the 12.19” rotor spec kits for SCCA American Sedan, the Pony Car group has been expanded to include 13” rotor kits with four piston calipers for NASA’s American Iron categories and the Camaro-Mustang Challenge. These kits are engineered for full compatibility with the common OE master cylinder/vacuum booster combinations, or any car that has been converted to a manual pedal with appropriately-sized master cylinders. Spec37extreme-duty alloy GT Series directional vane rotors, race-compound pads, mounting brackets and all necessary hardware are included.

MSRP starts at $1,988.00.
