Mk1/2/3 23.8mm Master Cylinder Upgrade

Regular price $209.00 Sale

MMP's 23.8mm master cylinder upgrade for Mk1/2/3 platform VW is the perfect upgrade for our BBK's requiring a 22.2mm and larger master cylinder. Brake response and feeling is dramatically improved without sacrificing effort on brake booster equipped cars. An amazing upgrade without having to go to a non-boosted brake setup 

-Drop in application for most Mk2/3 brake boosters

-Mk1 applications require Scirroco 16V brake boosters or Mk2/3 booster conversions
