Running 17x7.5 Wheels?

[New_Daily]

Hey All,

Initially I wanted to stick to stock size wheels to re-use my stock tires and not have to worry about rubbing as well as not negatively effecting MPG. But it's looking more and more like any wheel I like I might have to go for 7.5 width.

So, wanted to check with those that have used 7.5's: will I rub when I have the car lowered? I'll running Swift springs (ordered them Friday), and was there a significant negative impact on gas mileage?

Thanks

As an aside, there are 2 models of Rota wheels I really like that show on their site as being available in 17x7 and 4x108, but I cant find them anywhere for sale. The GR6 and the SDX.
