A good friend of mine has a 97 GTP that is lowered and has a lot of mods done, it runs low 12s and we are shooting for high 11s this year with it. Anyways when he goes WOT the front end feels like it shakes and vibrates pretty bad. The car has had an alignment and does this with numorous sets of rims/tires though his daily summer rims are 20" with very low pro rubber so as you can imagine really amplifies the problem. He mentioned to me today something about reading that shortened upper motor mounts helping out with this issue and didnt know if anyone else has tried this. Then we got to looking at his upper mounts and he noticed the ones he found that were shortened look like stock ones and figured he could just shorten the stock ones but by how much? Thanks for those who can help out!
