what are the effects of using rims that are not staggerd. ie. all for sides are the same width....
and if so which width would u use??

 

No stagger = oversteer. More rubber in the back the better.

I am o.k. with my 225/40/18 and 255/35/18.
I would like to run 225/40/18 and 265/35/18...but I am trying to keep the same overall diameter for front and rear.
