I'm going monday to get my wheels flushed and wanted to know on a '14 sv with sport that came with the black 19s, is 20mm front 25mm rear correct? I am not lowering the car, just want it W I D E. I don't want the rims sticking out or hitting the fender at all. I will post before and after pix. I'm going to an h&r trak+ dealer to get them installed

 

put a level against the fender.
Measure from level to wheel.
Buy that size spacer.

or

go to dealer
tell them to make it flush

 

I have some 10mm H&R hub-centric spacers that I could get rid of if you're interested. They were never used but you'll need to replace 2 bolts. I'd take $90+ shipping for them
