I think the amount of scrub while making for good feedback with ps, made manual steering not a factory option on the solstice. The smaller tires help a little but still about 1-1/2 inches. I'd keep the ps or leave room for a pump on the motor later if you want to add it down the road.
I'm saying camber loss in that during straight ahead braking, the wheel tilts away from 90 to the surface, the contact patch goes away/concentrates on the edge of the tire to reduce traction/overheat the rubber above where loading improves traction. A compromise between one wheel bump and gain in roll.
That makes plenty of sense. Finding a wheel with that much offset might be impossible... I could machine the hub to get a bit less scrub, but I doubt it will make enough of a difference. I plan to run a manual rack but will definitely keep in mind that steering effort might require a need for PS down the road.
Camber gain on braking was excessive... I see that now... If I raise the upper control arm mounting point I can get significantly less camber gain under braking, lets say ~1/2° per inch of bump, but my outside tire camber goes to 0 with around 2° of body roll. I suppose once I take into account camber gain as a result of caster angle, it should balance out. Also I suppose its a lot easier to correct excessive body roll using a sway bar than it would be to adjust damper settings for brake dive.
