This complete kit adapts Brembo/Porsche 4 piston Boxter rear calipers to stock 911 rear trailing (banana) arms (69-89) with 3.0" bolt spacing.  Can be used with aluminum or steel trailing arms.  Designed to work with 20mm wide rear rotors (69-83) but can be modified to work with 24mm wide "Carrera" rotors (84-89).  When installing this kit onto aluminum arms the small upper backing plate tab must be cut off each arm for clearance.

  • CNC machined
  • Anodized for great durability
  • High quality metric hardware included
  • DOT stainless steel braided lines included with grommets and banjo bolts
  • We can provide the calipers (new or used) and high quality German made rotors if you need them.
