Hey WiLL, thanks. I took my own car to the Firestone in Newark. They're ok but it's pretty much the only place I've brought my cars to get alignments. I purchased one of their lifetime alignment deals last year when I first lowered Fodoho so I'm pretty much "stuck" with them. I don't think they adjust camber or caster though, only toe, so I don't know if they'll add and remove shims in the rear. It's pretty easy to do that so I would assume they would if you asked them to.
My friend was supposed to try to get an alignment during his lunch break the next day at a Firestone in Mountain View but I haven't talked to him yet to find out how that went. This installation just happened this last Sun so I haven't followed up.
Oh, and $120 is a LOT. For that much, I hope they do custom alignments and put your weight in the driver's seat while they make adjustments and stuff.
