My 87 has 15x8 American Racing AR-23's; I'm not sure what the backspacing is. Tires are 33x12.5 BFG AT's. I'm getting contact in hard right turns, between the left front tire and the draglink rodend at the pitman arm. The inside edge of the front wheels are VERY close to the tie-rod ends, too. There's only 1/4" between the balance weights and the rodends on both sides. I'm planning on moving up to 15x10 wheels when I get new tires. Is this a case of improper backspacing, or could it be something more involved? What is the proper backspacing, anyway? Should I mess with the steering stops, and how is that done, anyway? Thanks for the help. Semper Maintenance!
