M3 E92 harsh vibration and clunking:Help

Alexei9012 · Today, 02:40 AM

Hi guys, I just got my engine and transmission mounts changed to stiffer ones, didnt have any problems or noises with the car before hand. Now when I accelerate between 2000-4000rpm the car has a harsh vibration in the rear and there is a random clunking when I slow down. Think it’s the centre support bearing but not 100% sure. Can anyone help?

solid transmission mounts create vibrations in that range, what mounts did you install?
