This Kit adapts Brembo/Porsche 4 piston 996 or Boxter S 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 be used with OEM 996 Carrera 24mm wide rear rotors (99-08).  Kit will work with 15" or larger diameter wheels providing enough offset for lateral clearance of the inner spokes, like a Fuchs 15x7, 15x8, 15x9, 15x11, 16x7, 16x8, 16x9, and all larger sizes. 
 
Note - When used with steel trailing arms the adapter brackets should be shimmed inward about 2mm to compensate for the thickness of the missing water/dust shield bracket.  The water/dust shields are not needed and most often not wanted, but they can be modified to accomodate the larger brake caliper if desired.
