How bad was the instal. I did my front and rear motor mounts and want to do the side motor mounts and the dif mounts. Can I do it with simple hand tools?I do. Run them both and can't believe how important the cam and transmission side motor mounts are. A big difference and tightens everything up. I can't speak to vibration as it is a race car and so vibrates so much it's hard to tell.
The rear diff mounts help too, mostly in their reducing flex and movement when shifting power, down shifts, and on corner exit. Getting to power is faster, more abrupt and immediate. Again, for our application, a vey good thing.
