I got my car as a wrecked sale and I had to go through and replace alot of body and suspension parts. One thing I didn't check was the engine mounts. Drove the car for a month and the clutch and shifting was really crappy, acceleration sucked and so forth. I went through and replace em with engine stiffeners solid engine mounts and holy smoke. All i can say is night and day. The 2 that were ruined were the lowers on the drive and passenger side.
