New car- Need Advice

I had a set of 15 inch steelies made several years ago, did custom backspacing for me, brought my car to the shop, along with the wheels, they were able to tack them up quick and set exactly what I wanted, a good shop should be able to do the same for you.
What you need is a pair of 14" sbp steelies, and a pair of 15" GMC S15 rally wheels from around 1990 or so, or a pair of Oldsmobile Super Stock 15" inchers. Have the centers cut out of both sets, and the hoops from the 15s rewelded to your sbp centers. When I had mine done about 10 or 12 years ago it cost me around $150.00, plus I supplied all the wheels.
