ZZP W-Body 12.7" Four Piston Brake Kit

This brake kit is the perfect upgrade for anyone looking to massively improve the stopping power on their W-Body platform car, all at a reasonable price. The kit uses standard sized GXP (12.7") rotors as a base, so replacements are readily available and easy to find. We then use a custom ZZP caliper shim to center the 4 piston ZZP caliper correctly onto the rotor for even pad wear. This kit is easy to install, easy to service, and is a huge upgrade over the existing single and 2 piston floating caliper brake kits available. You will have a stronger, firmer pedal feel, reduced stopping distance, and less resistance to fade with the larger rotor and increased pad surface. Fits all W-body 3800 cars, W-Body LS4 cars, and H-body cars. Fits 18" wheels and up, may fit some 17" wheels. As with any big brake kit, fitment depends on wheel size, offset, style, and spoke design. You may need extended wheel studs and a wheel spacer to fit your desired wheel. The stock braking systems may have been
