Dont be tricked by the pictures on the gm website the rim are actually lighter than what they show on there. more of a dark silver than black. I looks awsome in those pictures with the black stripes and gfx but the rims are not that dark. just FYI. Other than that IBM!!!
Here's a picture of mine..so you can see what the rims w/ RS look like.

Edit: Unless your getting black rims then your all good to go
