As per MM instructions for street cars and what i have heard elsewhere; Positive caster can be increased as much as possible. There effects of 1 degree change in caster is negligable so 3+ degrees is fine. Increased positive caster with increase the amount of negative camber on the outside wheel when turning hard. That is why positive caster is more desireable. Apparently -0.5 degree of toe (toe-in) is normal and desired for stability. Every adjustment to the toe will drastically effect the camber. So Camber should be adjusted last to about -0.5 degrees +/- 0.25 degrees. I dont want my tires to be wearing out any faster than they already do!? So i want to keep the camber in check, as too much neg. camber will really wear tires out quickly. Anyone else have any input? Road racers?
