New rear brake conversion kit for your F3x F2x BMW. This will allow you to run 15-inch wheels and tires on the rear of the car, perfect for drag and roll racing purposes. Using lightweight Wilwood Dynapro 4-piston calipers you won't have to sacrifice stopping power. 

Even if you aren't looking to run a 15-inch wheel this is still a very good upgrade over the stock 1-piston calipers! Contact us if you want to run a larger rotor on this kit instead of the standard rotor.

What's Included in the Kit:

  • 2 Wilwood 4 Piston Calipers (Red, Black, Grey)
  • 2 Zimmerman Rotors (Drilled or Plain) 
  • Rear set of high-performance Wilwood BP-10 Pads (Or source your own)
  • All brackets and hardware required for installation
