TDI drivers have been looking for a way to firm up engine location without making the car unpleasant to drive. Polyurethane mounts are known to transmit excessive vibration to the body in TDIs, and aren't a desirable solution for most daily drivers. We think we've found the best of both worlds from 034Motorsport: mounts that are stiffer than stock but provide much more secure engine location. These high density mounts are 60 durometer rubber, about 25% stiffer than stock mounts. The result: dramatically improved engine location with minimal increase in vibration transmission.
