being that im swappin in a 6bolt soon for my car, i figured id get this upgrade while the motor was out anyeverything. so what are your experiences with them? ive read that the prothane mounts HELLA vibrate...is it annoying? i know the ES dont vibrate as much but im wonderin if there is noticeable difference or not. i dont race that much but i do make it to the strip every once in a while if that matters. TIA

Vibration or Earthquake
