You won't have any problems running 19's, I run 19x8's on mine without a problem. The awe factor of 19's is awesome, gotta love it. As for the performance aspect, unless your building your car for all-out hauling ass speed, the minimal difference will be well worth it. I don't have a turbo, but I do run nitrous, and my performance is good. I've got the power to run / outrun most people, and the show-stopping capability that breaks necks and wins the shows. Go with the 19s and never look back!!
