Some follow-up:
I just drove highway 108 through the Sierras with (5) people, two heavy coolers, and a large PA system (with every other nook and cranny of the car jammed full of stuff). Loading the car to the max really helps accentuate any compromises one's made to the car (like messing with the scrub radius). It definitely didn't handle great.
The road is insanely steep and wind-y in places, and a regear doesn't feel absolutely necessary, but there were two or three instances where the gearing felt way off and I wasn't able to go faster than 5-10 mph up really steep pitches.
There's an issue with my PCS system that is noticeably messing with my traction off road while driving fast. But I think that my scrub radius may also be compromising my traction. I'll get the PCS system worked out and report back.
Thankfully, my car will very rarely, if ever again, be weighed down this much. But maybe I'll trade the 0 offsets for 25mm offsets (check the classifieds!). And can't wait to install the body lift.
