Wouldn't the width of a tire exaggerate inside tire wear if the camber is too neg.? My son also contends that when he had the front of his Gen2 Intergra aligned to spec (with a camber kit installed up front & the longer bolt & washers deal on the rear, that dialing the front end into factory spec made the rear neg. camber worse than it had been. I think his Integra has a combination of issues - already worn-on-the-inside rear tires that were rotated from upfront, aggressive cornering, wider than stock wheels/tires, and a toe out of spec in the rear, and possibly at both ends. (he's riding on 15"/50series tires on 15X7 wheels, H&R Sport Springs & Tokico HPs, and a stiffer & beefier rear sway bar)

Would a lower 'tie-bar' help in the rear to limit movement that's a function of older bushings, etc.? The front of his Integra seems much tighter w/ the install. of a strut-tower brace, and I suspect that a thicker bar up front would limit some adverse tire wear - at least when in certain segments of a turn, when a lowered suspension is not quite in alignment due to geometry changes, and for the typically much wider footprint from upgraded/lower-profile tires.
