I have low mileage ZQ8 bilsteins and they were a definate improvement over stock but still don't seem as good as they could be. I'm just wondering if the weight distribution difference between a wheel spaced out with rim offset vs. spacers is enough to notice? the total weight difference between my stock 15" alloys and the T/A wheels with spacers is only ~6 lbs.

Are the stockers 15x7 and the TAs 16x8? I would think the difference you are feeling is due to different size tires. Did you weigh just the rims or rims and tires?

It definately could be just the difference in tires that I'm feeling but the wheel/tire combo is pretty close to a stock ZQ8 so I figured the shocks would be valved to suit them. I've never driven in a stock ZQ8 truck so I really have nothing to compare to

IMO the weight isnt that big of a gap. I think the trend in the automotive world is by moving the wheel offset outward, gives a better aero flow across the wheel surface and limits drag. But also to maybe give the wider tracking feel. My opinion differs in that a more centered hub will give the better feel in cornering and tire wear.
