Wheel spacers are also a great tuning tool to help out with over/under steer.

Yes I was running front and back spacers. I had them off the other day to swap to other rims and they are actually 1.25" and not the 2" that I thought. In an ideal world I wouldnt run them but after an entire season of running them and not having any issues I would do it again if I had to. Also as a side note, my s10 still has the stock-ish 4.3 and a 5 speed, by no means a power house. I think max hp in that thing is 150 and that is being very generous.

On my Cobra replica AXing on 315 A7s I ran 1 inch spacers on the rear for several years. I got Eibach hub centric. They were the style intended to bolt to the hub and then the wheel bolt to them. Expensive but I felt real comfortable using them like this. I knocked the short studs out of them and slid them on the 3 inch ARP studs using the holes that were originally intended to bolt them to the hub. I used the included slightly thinner nuts to torque them in place. So basically I had a wider rear axle. I figured the empty holes where the studs used to be were lightening holes.
