Show original supplier description
This kit includes Dynapro Dustboot calipers with dust-sealed aluminum pistons, offering enhanced protection against road and track debris, making it suitable for applications that operate in harsh environments or require increased piston sealing. The kit is paired with 12.19-inch diameter rotors and high-performance Wilwood brake pads to deliver substantial braking improvements over stock systems. The Dynapro Dust-Boot calipers feature a 4-piston design with a 1.75-inch bore for each piston, totaling a piston area of 4.80 square inches. They utilize the 7812 brake pad plate with a pad area of 6.36 square inches and a volume of 2.1 cubic inches, compatible with BP-10 brake compound. The kit includes black powder-coated calipers and plain face or drilled and slotted 12.19-inch rotors, with options for caliper finishes and rotor designs available to suit various customization needs. The OE hub offset is +.19, which may affect track width. Installation details and fitment require careful consideration. This brake kit is compatible with Drop Spindle, Factory Disc Spindle, and Factory Drum Spindle types. It is compatible with vehicle makes including Buick, Chevrolet, Ford, GMC, Heidts, Mercury, Oldsmobile, Pontiac, and Ridetech, though Wilwood advises calling for specific fitment on other vehicles. The kit may fit some 15-inch wheels, but a wheel clearance diagram must be consulted before purchase to ensure compatibility with your specific wheels. The hub offset of +.19 will move wheels inward or outward by that amount on each side.
