Thanks for the input guys. I was major pissed off when the dealer told me they couldn't do anything because it's aftermarket stuff. I just ended up wasting $90 ..
I'm taking it to an independent shop tomorrow morning. I talked to the manager and they've done alignments with lowered cars and aftermarket arms so I feel confident that they'll do it right. He was telling me how negative camber is good for handling but bad for treadwear. So I'll have to think about how much camber I really want.
If it's at -1 to -2 degrees, will rotating the tires fairly often offset the uneven treadwear?
Good call about bringing the SPC instructions, I'll definitely do that.
Is it a performance shop? Long story short. I replaced the shocks on my Civic with lowered springs (H& Sport), the car still tracks fine, but I figure it was the right thing to do to get an alignment. So I went to Big O Tires because they (that one) IS on the list as a Recommended Installer for lower springs, coilovers, etc - according to Tirerack.
They messed it up so bad, and give it every reason in the book why they could not get it right. The car drove horrible. Even the manger said, there is nothing they can do, and refuse to re-check it. Wasted $75.
So I went to a performance shop. They said "no worries" and got it aligned perfect. Drives like a champ.
This is where you have to look at the workers and not trust what the shop said they can do. If they look like tunner car owners, then they know what they are doing. Look at the employees cars parked in the back/side.
If they just look like regular wheel and tire guys, ASE or not, don't mean they always know what they are doing.
That was my experience.
