You can't see it from the rear so I could care less, just FYI. The only reason mine are so close is because I had some tip clearance problems due to (we believe) the output location of the Stillen short-tube headers that are currently on the car. I used washers to space off the rear hanger bolts to give even that much clearance.



Honestly from the pic the clearance and side-to-side difference looks pretty normal to me. Maybe if it were up closer or if I could move side to side and stare at the angles in realtime, I'd notice, but I donno.
