It's my first post on this forum. I have been searching for info on this topic, but I can't seem to find any, so here goes...
If I go with 20" custom wheels on my 2013 CTS AWD Coupe, do they need to be staggered sizes (i.e. different widths between the front and rear) like stock? I have been shopping for wheels and tires on CARiD.com, and the wheels that they say fit the car are the same size front and back.
Given that my car is AWD, I am concerned about maintaining the proper revs/mile ratio between front and rear, and I have read that keeping this ratio at 1 to 1 is the easiest way to do this. Using the same size tires on the front and rear obviously accomplishes this, so I was thinking that going with a non-staggered setup might be the way to go for this reason as well.
Has anyone done this? Any help would be greatly appreciated!
