Wilwood 55 56 57 Chevy Full Size Car 56 Corvette 12″ Rear Disc Brake Conversion OE Axle: Adding disc brakes to your rear axle will create the best possible braking combination for your full size American car. You will notice shortened stopping distances, reduced fade and improved brake feel. Our bolt on Wilwood Pro Series Kit utilizes a large 12.19″ vented .81″ thick iron rotor. Inside the rotor are Wilwoods patented internal e-brake with huge holding power. This hidden mechanical e-brake is designed to easily mate with your OEM cables. Clamping duties are accomplished with the Wilwood 4 piston Dynalite forged aluminum calipers.

Considered one to the best calipers made, these slender units incorporate stainless internals and use an “over the counter” shaped pad. This great looking package creates huge stopping power, quicker cooling and is constructed of long life components designed specifically for the heavier US full size car.
