Our 70A poly transmission mounts are the solution if you are trying to improve performance while minimizing vibration and NVH. They are 'bolt-through' style mount which means the bolt goes through the entire mount. They are comparable to BMW Group N mounts in hardness and are 30% stiffer than the stock mounts, which makes them perfect for weekend fun cars, or the occasional autocross.  Currently they are the softest polyurethane mount on the market, and we suggest these for most street cars. If you are building an all out track car, get our solid transmission mounts.

Fitment: e30 - 318, 323 & 325
