If they change the caster to give you more room, you'll end up with less caster, and you really don't want that. The part that would bug me is the .3 and .4 of Camber.... they should be able to dial that in to 0.0 or at the very least 0.1.
My caster is at 2.0 and it's a good thing.
If I’m reading this and other stuff correctly, camber is more important than caster (at least while I have smaller tires and not rubbing). So if one or the other to spec, it’s camber.
Let me see if I have this correct:
stock spec for camber: -0.3° through 1.3°
stock spec for caster: 2.0° through 3.5°
The only thing that changes for a 2” lift is a target camber of 0° (Slightly lower than middle/target for stock)
So if I can get my caster around 3 or just below AND my camber at 0, that would be ideal, correct? With how adjustable the SPC upper ball is that should be easily achievable I would think.
