i think they are the same i haven't measured them yet but is there a way i could get more backspace on the front tires because i have grown attached to the current rims and the difference is more than a inch at least
First thing to do is to get 'ungrown' to those cheap generic trailer-wheels.
A factory steel wheel with a hubcap would tuck in the wheels nicely and look better at the same time as well.
Then you could go with a 1 or 2 inches wider wheel in the rear to lessen the front/rear trackwidth.
