The TyrolSport Master Cylinder Brace dramatically reduces master cylinder/firewall deflection and greatly improves brake pedal response by bracing against the brake master cylinder. Please specify if you have a CC or a B6 Passat, as the chassis requires a different stop. The MasterBracket does NOT fit Mk2 Audi TT. Installation is relatively simple and should take about 25 mins. CNC machined from 6061 t6 billet aluminum.
