wow man, lots of issues going on here. i have some input, being that i know a thing or two about cars.
first of all, you went to the wrong shop. ive never heard of Les Swab or whatever, but it sounds like just another "National Tire and Battery" or generic shop. the reason they looked at you like you were crazy is b/c they dont know anything about a performance alignment. all they know is "i have to make the arrow on the computer screen turn green instead of red". an alignment is a very intricate (sp?) repair that requires the tech to actually know what hes doing, especially in the case of having a modded car. if not, he can actually make the car drive worse (which it seems he did). i dont think you said you had C/C plates, but hes feeding you a load of BS saying that the Caster is 'maxed out' b/c our car's caster is not adjustable from the factory. not many cars are anymore. thats why we buy Caster/Camber Plates, so we can further adjust Camber, and allow Caster adjustment.
Next, i wouldnt go back there anymore. i would demand my money back and go to another shop. every time you bring the car back, they have to align it for free again, and they hate that. theyre not gonna do a good job, theyre just gonna do good enough for you not to come back, or hope you get fed up and never go back.
As for one of your questions, its really not too hard to tell if your tires are wearing badly. if you drive down the road with the wheel cocked to one side, or the car pulls, chances are youre wearing badly. the harder the car pulls, the more theyre wearing.
So what would you suggest my settings be at then? Sounds like you are in the "get c/c plates" club. It's funny that you say the caster is not adjustable, I wonder why nobody else picked up on that fact and have been telling me to adjust my caster even though I have said multiple times in this thread I don't have caster/camber plates. Dropping my car has been the biggest BEEYOCH. If I would have known that C springs would caused me this much grief, I would have bought some more aggresive springs, C/C plates, and called it a day.
