hey im about to buy a used set of wheels and they are 19x9.5 on 235x35 tires all around im wondering are there any risk in running a square set up on my 05 coupe? im on stock 19s right now running staggered. and how would they look if thanks.

..No..

so it would be the same? like does anything change ? pros and cons?

It will practically be the same. As long as the front and rear tires are roughly the same height, which they are, you will not experience any VDC issues.

^^^what he said.

i thought the car came from the factory staggered so it must be some reason it came like that.. So it has to have some effect somewhere if he doesn't have a staggered setup.. thats my 2 cent

I run 265/35/19 all around and the car is fine. You will hardly notice any difference - though at the absolute limits, you will also reduce understeer.
