I installed the hasport mount kit in my 94 coupe I didnt mind that there were small vibrations. I can notice things in particular vibrating that maybe I can fix/tighten/or sound deaden. But, my question is.. I drove in a 96 hatch with the same hasport mount kit as me, and his car was so much more tollerable. We both have the street kit. The only difference is he bought his used. Does this mean that my mounts will break in over time, and absorb more vibrations? His car didnt rattle at all like mine. I checked, my kit is 62A street kit. So do hasports require a break in period?
