 Kit highlights

  • With our CNC-machined, aerospace grade 6061-T6 high strength caliper adapters, mated to the finest lightweight Wilwood 4 piston calipers, we were able to realize a massive weight savings of a 60% unsprung weight reduction over the factory 9.4" caliper assembly, while gaining significant performance increases.
  • Wilwood Powerlite calipers were chosen after extensive testing. Because of the small size of the 239mm disc, we have found that using larger piston calipers actually lost performance through rotor overheating, difficult brake modulation and overly sensitive lock up. Using a 1.38" piston caliper translated to a favorable static bias increase over the Mk1 calipers, but allowed more fine tuning of bias through pad compounds. Bigger piston calipers aren't always better, especially in a Mk1 watercooled VW!
  • Powerlite calipers, a well established Motorsport caliper use in many categories, use a single split bridge design which translates into better pedal feedback and reliability in racing and high stress situations. These calipers are bulletproof and punch way above their weight!
  • For a small caliper, the Powerlite offers a big piston area increase over the factory Mk1 calipers, and a pad size which is perfectly suited for the swept area of the 9.4" disc. We are fortunate to have been able to collaborate with Wilwood on this to produce this kit.
  • Wilwood's Powerlite profile is extremely compact, but with uncompromised performance. There are no kits on the market offering this level of clearance! Our kit will fit most cast 13" and 14" single piece alloys, pending wheel style
