Simply put, the toe-in condition coupled with positive caster and negative camber, will concentrate all of the tire wear on the very inside edge of the tires. Yes Bob,this issue is concerning the 53 210.I always make sure I use the proper forum for my questions.But I would rather ask the question here,than on the VCCA forum,too many people just telling me to read the shop manual over there with no real useful info.Not always,but most of the time.

Not only it provides excellent control over the steering but also a negative camber provides more high cornering speeds on any vehicle. I added a 1/4" to each side and the left front was nearly neutral but the right still had a quite a bit of negative camber. The control arms, top and bottom yellow parts, are usually adjusted by cam bolts or eccentric-washer bolts to effect camber and caster changes.
