Possible good point on the spring sag.

Outside tire wear led to a service bulletin that had the front (of the two) strut mount bolts redrilled inwards. A similar thing has become known as the 'camber mod', and I did it to my car by slotting the front hole in the tower so the mount could pivot inwards. I moved the front inwards only a small amount, maybe 8mm, and it made a noticeable difference. I'm going to get an alignment and have it precisely set at -1deg.

Caster, some put washers hehind the rear conical bushing. I may do this also.
