did you tighten ur vibration dampners all the way? I got a similar problem w/ my injen cai. It hits against the sidewall when I have a slow start in the morning. But I havent had any problems while driving. I was thinking a good solution might be to pad the sidewall w/ a small piece of styro-foam and some tape. It'd still be hitting something, but wouldnt be leavin those dints.
