I Have A 92 Rs With A 305 And I Want To Put 17's All The Way Around.i Was Wondering What Is The Widest Rim And Back Spacing I Can Put In The Rear Of The Car(i Like The Deep Dish Look) And What Tire Size Would I Run Without Hitting The Fender Lip? I Know The Fronts Won't Be As Wide As The Rear So Any Help Is Appreciated!!
