I know what your talking about Tommi. The caster angle should be around 2 degrees positive. The upper strut bearings will be behind the spindles if you were to look strait down at the front hub.
*More negative caster may make the steering easier, but may also make it harder to find the steering's center while driving.
The car will pull towards the side with the least positive caster, and pull towards the side with the most positive camber. Caster angle doesn't generally adversely affect tire wear, but camber angle, and excessive toe in/out do.
-*edit;
after a cup of coffee this morning, I realized I made a mistake. Negative caster was what I meant to type.
thx Volkdent.
