These mounts are designed for all BMW E90, E91, E92, E93, E82, E81, E87, and E88 cars with an N54, N55, or N52 engine (excludes the M3). They are rebuildable and the polyurethane bushing inserts can be easily swapped out for a different hardness. These mounts are made from CNC machined 6061-T6 billet aluminum combined with high quality polyurethane. Revshift mounts are the most durable and reliable mounts on the market. To further ensure the strength of our mounts we form the threads with a forming tap which creates denser and stronger threads in the billet aluminum pieces. The polyurethane compounds that Revshift uses are among the best for automotive use and exceed the material quality of possibly all other automotive polyurethane manufacturers.
