Do you have to run the 17's (brake clearance)? If not and they are who you want to use, swap wheels. If not, find a place that can work with your car. Most alignment heads stick out 3-4 inches from the wheel edge, and extend up and down maybe 20 inches. See http://www.prealign.com/images/hunterman.jpg It could very likely have clearance issues. Different machines have different heads. You may have to check around to find a place that has the tools to work with your mods.

If they are truly saying the didn;t have the right equipment I would be curious how they did the Camber and Toe.
They were able to do toe-in and camber but the guy said that in order to do caster the head had to be ratated like 30 deg both ways but the heads would not clear the fender? Something like that anyway.

Are they saying they DID adjust Camber and Toe?
If so, what they may have ran into was that in getting the camber set to spec (which you really DON'T want BTW)the caster ended up being less than optimum, which is common in our cars, expecially in a car that may have been crunched at some point.
They did get camber and toe...1" neg camber and 1/16" toe.

GOOD numbers there! (You don't want postive camber, even though stock specs are positive) If you didn't tell them you wanted 1 degree neg then they already knew---thats a GOOD sign. Sounds like they don't have the right head style to clear your fenders with your 17 inchers.

They're right when you turn the wheels on a lowered car the heads can get close. If it steers straight and camber & toe are good I wouldn't worry about it.

Can caster be adjusted without affecting camber since they are on the same 2 bolts, or would the camber need to be reset after turning the bolts?
No. The same two bolts. One affects the other.

You have to do camber and caster adjustments at the same time.
Try finding a shop that has a Hunter DSP 4000 or newer machine. I use a DSP 4000 at work and I cant remember the last time I had a problem with getting the heads to mount or read.

Now thats the answer I was looking for...thanks!
I notice that the car darts a little when I go over a ridge in the road...sorta like driving on the old bias ply tires. I assume this is due to a caster adjustment...since the tires are new and my camber and toe in are now correct.

i don't do alignments for a living but my buddy lets me use his alignment machine to do alignments on my car.
to the best of my knowledge you have to do a caster swing to get any readings, including camber and toe, from the alignment machine. how were they able to get the other readings without doing a caster swing.
they have a hunter hawkeye machine at the dealer where i work. according to the alignment guy this machine can do alignments on all cars with wheels up to 24" big.
perception is 90% of reality

Thing is, when you find a shop with the right equiptment, they will likely have to redo the camber and toe too. They'll probably have to start all over again.
Not having the caster equal or close will cause the car to pull at cruise speed.
My car is lowered with 15" wheels though. Not a problem. I don't see how 17" rim would make a difference in the setup shown in my picture...

I need to make one small correction due to my bad memory. The alignment machine is a DSP 400 not 4000.
Sorry if that caused any confusion.
