Looking for your advice on backspacing... I am looking to add a set of larger rims for an upcoming event (more on that later). It’s basically a 17” version of the wheel used on the Sam Posey Challenger. Here are my questions: a) will a 17x8 wheel with 4.5 backspacing work on the front? b) assuming no issues with a 17x8 wheel with 4.5 backspacing in the rear? c) will a 17x9.5 with 5.5 backspacing work in the rear? d) if I could have these made to order, what would be the ideal backspacing for a 17x8 in the front and a 17x9.5 in the rear? Thanks guys, really appreciate your thoughts.
