Niche Targa's

[NAVAG]

After about a year of countless hours spent looking at different aftermarket wheels online and on other cars I think I have decided what I want.

I think my car will look really nice in a set of Niche Targas. Here's a stupid question:

19 X 8.5 + 35MM Offset 245/40/19 Front
20 X 10 + 40MM Offset 285/30/20 Rear

Anyone else try a staggered set up like this one? Or should I go either 19's or 20's on all 4.

Only other decision I need to make is color. Not sure about black wheels with black car...But right now I'm more concerned about proper fitment.

Also, for those of you that purchased the Niche wheels, What lug nuts will work best?
