I just put on new wheels and tires 949's 17x10 in the read +72 with 275 NT05 and 9's in the front w/ 255 nt05. The car has some sort of lowering springs in it, not sure what they are as they came w/ the car. I also have some fender rolling. Fitment is good, however on bumps if I'm going too fast they will rub a bit. Is this acceptable?

 

You have to decide if it is acceptible. You have a very wide wheel and tire package on the car. You can try running more negative camber if it is rubbing the fenders.

 

Where is it rubbing ?? In the front our at the back ??
When it's rubbing at the back it might help to replace the top bolt on the rearbumper a bit back . And you can trim the back bumper a bit . That's what I did with my car .
