These precisely machined adapters convert your standard 911 rear trailing arms (Steel or Aluminum from 1969 to 1989 with 3" bolt hole spacing) to allow you to mount Boxster S or 996 NA rear calipers (1998-2005), while running the beefy 996 (1998-2005) 24mm thick rear rotors. EXTREME stopping power and GREAT looks. Kit comes complete with TWO anodized aluminum adapters and high quality fasteners necessary for a quick conversion. May require a brake proportioning valve or bias adjuster.
