What bluNblu said,
and I still had to cut the lower corners of my fenders at the front, cuz when backing up,under certain conditions, the tire would grab the corner and want to rip it up.
If you really want to run 15 x8's, you are gonna have to move them as far inboard as is possible, and trim the upper ball joints if you have to, and move the wheelweights; whatever it takes! You will want to take the shock off and back out the T-bar, and cycle the suspension, cuz when the wheel moves through it's range of motion, you will need to know exactly where it is gonna be at all points.Then you get to repeat it on the other side, cuz when you're this close to the edge, the two sides are rarely,possibly never, the same.You just cannot assume they are.
I went back to 14 x 7's. Now I can drive the berries off it, and no worries.
Oh wait, I'm driving a 68 Barracuda.With a complete suspension from a 70Duster340. Your results may vary
