I am having some confusion on what back space to run on a front 15x6 Weld Pro Star wheel. I have 15x6 Buick Ralleyes currently, with a 3" backspace. Weld only offers a 2 1/2" , or a 3 1/2" backspace on their 15x6 wheels. I like a stock look, with the wheels brought out to the fender well, and a deeper dish. What are you guys running with that wheel size, and any recommendations would be greatly appreciated. Thanks, John
