Ive got a MS6 with the CP-e engine mount. Install is easy, just need a jack, car stands, a 10mm socket, and some big wrenches (sizes escape me). I like it. It eliminated the CLUNK and helped shifting. The car vibrates at idle more, but it is tolerable. It smoothes right out anything greater than 1000 rpms. I like it. But, if price is a concern, go for an AWR
