18x7.5 w/ 215/35R18 - 39lbs (19lb wheel, 20lb tire)

So, even with a lightweight 18" setup, you're both heavier than stock and a lot of that weight has been moved further away from the axel, so you'll definitely see a drop in performance.

Great point. I didn't see you wrote that, else, I wouldn't have posted what I posted before this. But you still explained better than me.
