I'm looking to keep the standard 15" size but I'm willing to go from 6.5 to 7
Also looking for ones that wouldn't require me to roll my fenders at all.

The ones that I've looked at are:

Gram Lights 57G 15x6.5 +38 or +45
Volk Racing RE30 15x7 +43
Work Equip 01 15x7 +35
Work Kiwami 15x6.5 +42

 

I just installed Konig feathers on my GD3 (15x6.5) and I love them, I wanted something light weight so these were perfect for me and I have no rub. My car is lowered on eibach pros and I have no issues unless I hit a massive bump. You shouldn't have any issues with 15x6.5s, couldn't imagin how much more rub you would have from 15x7s.
