Product details
This red D154 is the twin-piston, nominal 1.04-inch rotor-width configuration. Two equal 1.62-inch stainless bores provide a 4.12-square-inch area in the forged GM metric floating body. Wilwood Engineering, founded by Bill Wood in 1977, is based in Camarillo, California. The company makes and designs disc brake components and systems for motorsport, street-performance and specialized applications, including calipers, brake rotors, master cylinders, valves, fittings and brake lines.

Fitment & Compatibility
Check bracket and rotor dimensions before choosing the twin-piston design. The D154 pad shape and M10 x 1.50 banjo inlet must fit the existing brake arrangement without confusing it with the larger single-piston version.
Ask PMB Performance to check the complete brake arrangement before ordering. Our team brings over 20 years of experience; photographs and measured bracket and rotor dimensions make that check more useful.
