Would running a non stagger deter perfomance? The wheels are 3 piece so I can upgrade the rear lips to make the final width 9".

Specs on the wheels are

17x8.5 +55 ET.

no fender work would be require correct? Besides a basic roll of course.

Wheels in question. I am going to powercoat them, so dont mind the cheesy black face polish lip.

 

Some say a non-staggered setup results in slight oversteer.

Are you lowered at all? I think regardless, with those specs, you probably won't even need to roll your fenders.

 

No need to roll fenders!

 

I have 18x9 +55... you'll be fine
