H&R Wheel Spacer

[Jimc]

Before everyone freaks out I did read through all of the post in the sticky on wheel spacers but I am still confused.

I have a 2012 with Sport Package so 19 inch Rays. I want to add the H&R Spacers 15 on the front and 20 rear. I would like to use the bolt on spacers and not replace the studs, but for the front Stillen said the 15's won't fit the wheel.

Yet it does seem like others have been successful with this combo. Any comments appreciated. Very much a noob with this subject so don't beat me up too bad.

Thanks

Jim
