Will not fit factory Passat B4 TDI. This kit is for the VR6 models only, designed for use with cars that were conversion TDIs.
Front brake set B4 Passat GLX with a VR6 2.8L engine. The B4 VR6 models are often converted into TDI models. The VR6 Passat came from the factory with 5-lug hubs and larger rotors, rather than the 4-lug design in the factory TDI model.
