At 4K rpm's, in all gears, I get slight vibrations that I feel thru my steering wheel. It only happens when I stay around 4K rpms, doesn't happen when I'm just on the throttle hard and rowing thru gears.Btw, its a 6MT.

Any idea what this could be? Bad motor mounts? Etc....

Btw, its nothing to do with my wheels. Just had them balanced and aligned.

 

Just realized something...could it be the precats or jpipe somehow making the vibration?? this didn't happen before I started modding the car.
