OK, my bud is getting ready to order a set of Billet Specialties from me. He wants 15x10s. I have been doing some reading, and I am gathering that you can run a 15x10 w/ a 7.5bs as long as you relocated the sway bar?? Has anyone had any luck on the front runners? He wants a 3" or 4" front. Has anyone gotten away without a spacer??
