Track Alignment - Atlanta GA
Anyone know of a shop that will do a track alignment to customer specs AND is able to measure/adjust the rear caster?
Having trouble finding anywhere that will do this that's close to me. I actually live in Alpharetta, so closer to there would be ideal, but I'm willing to drive a bit to find a place.
Thanks

All you need is a reputable alignment shop. Purchase the required rear caster tools (adapter and a saw blade angle gauge) and ask a reputable shop to use them to set rear caster while setting rear camber. There is a GM TSB posted on the forum that provides instructions on how to set the track alignment including how to use a gauge to measure rear caster. It is simple to do although time consuming and anybody trained on using an alignment machine should have the reading skills to understand the TSB.
I attached the TSB so you don't have to search for it.

In the Atlanta area I would use Gran Turismo East, 3306 Shallowford Rd, Chamblee, Ga. 30341. Dealership that works with high end sports cars of all makes and models, does all Buyavette.net work on their cars. You can look at their website to make an appointment, phone # 770-455-0347. A little pricey but well worth it. I sure with their equipment, they can set it up to any specs that you want.

None of the alignment machines on the market have provisions for measuring rear caster. That is why the adapter and angle gauge are required. Any shop that says their machine can set rear caster isn't listening to you and think you mean front caster. Even some highly respected shops don't know about rear caster. Don't just talk to the person who writes up the order. Talk to the mechanic and make sure that person knows what you want and how it has to be measured. As for the track alignment specs most shops will think you are crazy wanting the settings you provide but will do the job, although I have had Chevy garage mechanics tell me the warranty won't cover any damage the alignment does.

That is good advice. In my research I came across a lot of the info on rear caster (a lot of it with you in the mix) and the appropriate procedure of getting it done. I actually spoke with the Gran Turismo East shop today without prompting them with info they were able to speak about the highlights, stressing REAR caster and using an angle gauge. As well as the difficulty in getting hold of the GM tool in the past. So they made their own. I imagine it's exactly what I have seen on the forum when I was looking.
As a side note, after reading many posts, anyone want to offer an opinion on running this set up for tracking? (2015 Z51 with mag ride on Michelin 4S)
Front : -2.5 camber, +7 caster, 0.05 toe in
Rear: -2 camber, 0 caster, 0.05 toe in

You might want to give Butler Tire a phone call. They always seem to have a couple of exotic cars sitting in the service bays. I am very particular with my cars, and they are very good at following my detailed instructions.
