Wilwood D154 Rear Caliper Kit - Black 1.12 / 1.12in Piston 1.04in Rotor

This Wilwood D154 Rear Caliper Kit includes the black D154 calipers with 1.12/1.12 inch pistons, hardened slide pins, and BP-10 high friction brake pads. It's designed as a direct bolt-on 2-piston replacement for many custom application rear setups that use the factory original single-piston "Metric" calipers.

These calipers feature forged billet aluminum bodies, stainless steel pistons, and competition-style high-temperature seals. This construction helps prevent the rust, bore pitting, and seal failures often found on OE calipers. The smaller rear piston sizing (1.96 sq-inches of area) is notable for achieving correct front and rear brake bias, which is not typically available with OEM calipers. You'll also see a significant weight savings compared to stock calipers, with reliable high-temperature performance suitable for both street and track use.

The D154 calipers mount in the stock location and can be used with most wheels that clear your original calipers. They utilize OE D154 brake pads and an OE M10-1.5 banjo bolt for brake line mounting.
