I plan on getting some 15x8 Pro Stars pretty soon, my question is, since my car is lowered 2" from stock, will they fit ok? Can I run less backspacing to make the wheels stick out a little bit (I like that look) and keep them from rubbing the fenders, or will I have to roll them?

 

I got 15 x 8 Pros stars for my car. To put them on the back I had to get spacers because they rubbed the brake caliper assembly. I think it was one 1/8" spacer on each side. Let me know if you need some, I could only buy a set of four from Jegs and I only needed two. the 15 x 6 prostars fit fine on the front.

I don't know about the fenders, I assume that would depend on what size tire you run. My car is not lowered and I had plenty of room, even with some 27.75" diameter Nittos.

 

What width (tire & tread) are you running in the back?
