Rapom's Rocket - just another Duster build thread
As I understand front rim fitment issues with stock A arms: 15" rims - backspace is limited by tie rod end and, depending on type of upper ball joint, the grease fitting. 17" rims - grease fitting problem solved but tie rod still limits amount of backspacing. 18" rims - tie rod clearance solved which allows much deeper backspacing. Now the width of the stock A arms can become a contact point at full or near full lock of the steering along with tire contact at the fender corners, fender lip and frame rails when trying to fit the max width tire/rim package in front. Fitment of any tire/rim is dependent upon the particular car and what the package of brakes, suspension components, ride height settings, alignment and the tire choice itself. Aftermarket A arms, along with their greater adjustability, are usually narrower than stock A arms due to the way they are constructed so that solves ONE of the problems.
