I got 19" wheels with H-techs springs. But the problem now is that everytime i drive on the freeway. It scratches either my rear fender or the underbody exhaust. (im pretty sure its the back exhaust) Why is that? it only lowered 0.6/0.3 .

Does anyone else have the same problem like i do??

 

Depending on the Offset you have for the rear wheels, you may be rubbing the tires when you compress the rear springs.....
You should see scuff marks on the rear tires if thats the case....
If so, have the fender lips "rolled" that should eliminate the problem......

 

What are the specifications for your wheels?

 

Yea, I would check my camber and roll the inner fenders if you have to. My friend had 19's on an Audi S4 and had to roll the fenders. Goodluck.

 

19x9 front 19x10 rear with right offset sets up.

 

Check the tire sidewall where it's rubbing (inner or outer). If inner, you'll want to
get a spacer to push out the wheel and new studs. If outer, you can half-*** it
by going to an alignment shop and asking for more neg camber on the rear for
clearance. Your tires will wear a little faster on the inter treads with more camber,
but as long as the toe is not far off, you should be fine.
