As a front suspension flex point, the rubber mount is a critical component in Porsche 911, 912, 914 and 930 suspensions. Original rubber mounts sag over time, so this easy-to-install mount kit was produced for replacing old rubber mounts. This kit is perfect for all street and race applications. The bushings are stiffer than original rubber mounts, yet are soft enough for supreme drivability on street and track. Made of a poly-graphite compound, this mount system keeps camber and caster adjustments at maximum specifications. This one-time fix can be installed on both sides within about 40 minutes. No re-alignment is necessary.
