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

If you're upgrading the rear brakes on a custom application that uses factory original single-piston "Metric" calipers, this Wilwood D154 Rear Caliper Kit is a solid choice. It's designed as a direct bolt-on replacement, meaning you won't have to do any custom fabrication to get it mounted. This kit gives you a significant upgrade over the stock setup, especially with its smaller rear piston sizing. This helps achieve a better front-to-rear brake bias, which is crucial for balanced stopping power.

What really sets these calipers apart is their construction. They feature forged billet aluminum bodies, which are much lighter than the cast iron OE calipers, and stainless steel pistons that resist corrosion and bore pitting. The high-temperature seals are also a big step up from what you find on factory calipers, which often fail due to heat. This means you get a low-maintenance, reliable braking system that performs well on the street and can handle track use without issue. The calipers mount in the stock location and can typically fit with most wheels that clear your original calipers.

This kit comes complete with Wilwood's hardened slide pins and their BP-10 high-friction pads, so you have the essential components to get your new rear brakes installed. You'll use the original style OE D154 brake pads and an OE M10-1.5 banjo bolt for your brake line connection, making the plumbing straightforward.
