I appreciate all of the responses. First off, I do not have caster camber plates since I was told multiple times that they weren't necessary with c springs. Secondly, it pulls to the left pretty hard. If I let go of the wheel, it tracks left immediately, I also have to correct for the pull to the left by driving with the steering wheel turned slightly to the right to go in a straight line. Next, I don't think its a simple tire issue. I have never had a tracking issue on my car and in fact had the tires rotated about 2 months before the suspension install. Basically, the alignment techs are telling me that they can't bring my right front camber any more positive. I argued on the phone with them for over an hour yesterday and I am taking it back to them on Saturday but this time I will be watching the entire process myself. They told me that all of my settings are within spec but I dont care. The car pulls now and it didn't before I lowered it. I've kinda come to the conclusion that I need to try to have them set my camber to -0.5* on both sides, as much positive caster as possible 4.0* maybe, and get the toe as close to zero as possible. And now after all of this I am getting this really loud banging / clunk noise from either the drivers side or passenger side strut tower when I go over certain bumps in the road. WTF????? I am really annoyed that I spent $700+ dollars and my car rides worse than it did on 5 year old stock suspension.
Here is the deal.....I have had a LOT of experience with alignments, not that I've done them, but I have experienced the ineptness of the $6.25/hr drones attempting to do them.
1. Most cars are FWD and the angles are built in with the exception of toe and MAYBE, camber.
Caster is a nasty word these days.
2. Most alignment shops haven't a clue how to PROPERLY align a car.
They have a $100,000 Hunter machine that even a trained seal can operate, yet they don't know how to use it and even if they do, chances are the machine has not been regularly calibrated and it will be off anyhow.
3. You are bringing them a car that "doesn't fit the mold" or the database that lives inside the machine. IOW your ride height is different than stock and your front end geometry is as well due to your height being off.
THIS is what is throwing the drones off the tracks. They don't know how to over ride the machine and do a custom job.
You have to understand, they are used to doing FWD cars and tweaking the toe a little bit until the *****'s on the display line up. Those are astericks BTW not bad words
This is why they are telling you that your car has been hit.
4. Find a speed shop that knows Mustangs, Camaros, BMW's etc IOW any high end RWD car and knows how to align them.
If you have no such animal in your neck of the woods, find a GOOD collision shop and ask them who THEY use to align the cars they put back together after accidents.
One last thing, and you are not going to like this, BUT, the drones may actually be correct.
Here is the reason why.
When the cars are built, there are certain tolerances in the manufacturing process that are normal. The adjustments that are allowed on the Mustangs suspension are there to make up for these tolerences.
So let's suppose, when your car was built you were near the + edge on camber, meaning the travel on the bolts was right at the top of the + side.
You would still be in spec, the car would track perfectly and you would be happy.
Now you go an lower the car and you need some more adjustment on that + sides camber. Well guess what? There is no more adjustment.
Yet, your buddy's car has all his stock adjustments in the middle, meaning he has adjustment play on the + and the - side.
And your other buddy may be more toward the - side so if he has to go more - camber with springs, he may not be able to.
Yet, all your cars are in perfect factory alignment WITH FACTORY PARTS.
Yet, adding certain aftermarket parts may be a nightmare for one of you and no problem for another.
See what I am saying?
All that being said, the short answer is find a shop that knows what they are doing and get another opinion.
As for the noises, that does not sound good....
Get it looked at.
