well i destroyed the lower mount when i took it to the track last year and destroyed a transmission. but i have been noticing something was off the past few weeks. so i went to flip my motor mount on the dog bone and chunks of rubber where missing from the bushing. just touched 90k on the gxp. i am just putting it up to its just the nature of a high torque fwd.

My lower mount was trashed too due to 40 + passes at the track when I replaced them two weeks ago. Well I actually replaced all of the mounts but the only one that was messed up was the lower one the rest were ok.

yea my lower was destroyed when the trans went out something about slamming into gear from a very high rpm.....................
and this was the mount on the dog bone. but i gotta say i am very impressed with the way it stiffens things up it by no means helps the situation when it brakes loose at 4k but you really feel the shift kit now!!!
(this thing came out like this using my thumb to remove it, and i was gentle)

Dave at TEP just replaced my lower mount when he installed my new trans. It was just wiggling around..
