I deceided to order a set of these just for the hell of it cause I thought it would be something good to have. Come to find out my front motor mount was wearing out and had a crack in it. It was still good but you could defienetly see the old age. After putting in the first one and drove the car around, these inserts made a big difference in the overall performance of the car. The drivieability and the traction is back. These do make a world of a difference. I put these inserts in at only 82K so for some of you guys with like 100k+ I would recommend it highly. Only $25 for the inserts. Only thing is that putting that rear one is going to be a serious bitch. Only way I can see is taking out the intake manifold but for now the front one is Excellent.
