im getting ready to order Weld v series bead locks for my 03 Cobra. The car has a SRA from a 99-04 GT and the Cobra brakes. My question is what offset for a 15x10 wheel. My choices are either 6” or 7”. Will I have to run spacers, BFH mod, roll fender? I want to run a 28” tire as well. I searched but couldn’t find anything definite. Thanks!!!
