Anyone want to adjust my caster for me? :D

[brtnstrns]

So with the autocross coming up this Sunday, I looked under my hood and noticed the alignment shop put my caster at max negative (at least as far forward on the CC plates as possible - with the aftermarket k-member and a-arms, it may not actually be negative caster). Otherwise, the car feels like it's in alignment. Anyone have any experience enough with alignments to help out or give me tips on throwing the caster back towards the firewall and fixing the toe to make sure it's not screwed up? I'm worried my car is gonna handle like absolute shit with this setup on Sunday and with my work schedule I couldn't fit in the time to get the alignment shop to set it up properly. Any ideas?
