hey, i was getting this jackhammer-like noise/vibration coming from the rear of my car after my SPEC Stage 3 Ceramic went in. Its mostly broken in now, i'm just wondering if the jackhammer-like noise/vibration coming from the rear could be wheel hop? I'm thinking it is, but not totally sure - has anyone else had a problem like this? I plan on getting LCA's and adjustable panhard rod here soon, so i dunno. If anyone has input, it'd be much appreciated - thanks!

 

Trans mount maybe. I wan having a similar problem when i hit the gas hard and I was in 1st gear. Might be the problem.

 

this is really mainly when i'm in first gear or when i downshift .... never upshifting 2-3-4-5-6 .... almost never....

i think LCA's would help tho... ill try it and see - any other experiences?
