C7 Grand Sport Track Alignment
I have a '17 Grand Sport and would like to get the track alignment specified in the manual. MacMulkin's where I bought it (2nd largest Corvette dealer in US) says that they do not do this. Another dealer researched it out and said that it would cost $350 since they have to remove lower fascia.
Is it really this big a deal?
Does anyone know of where in or near Massachusetts I could get this done?

I had my GS aligned close to DSC specs in Houston at Tracktime Performance. They don't have to do anything unusual to the car to do the alignment. Just make sure they have the rear caster tool. Should be $150 or so.

They do, my buddy that runs the dealership races Corvette’s and services most of the local racers as well. He said the alignment really makes the DSC come to life.

Great Recommendation!
I still do not have the rear caster checked or set. I had sent them the specs in advance and they replied that they could do the job......

Glad that worked out for you. I have recommended this place to several friends with all kinds of different cars and all have been very pleased with their work.

My z06 was roughly -1.2 up front -1.0 rear, a very good performance street alignment from the factory.
I had it aligned to the "level 2" DSC alignment for street/track. Its an agressive street/medium track alignment. -2.0 front , - 1.7 rear.
You can run the DSC alignment without the controller. The most important part is finding a shop that knows about the rear caster.

You dont get both, i.e. its mostly track OR mostly street or a middle ground.

The DSC alignment just refers to their preferred settings they have tested and recommend for these corvettes. I haven't installed the controller yet in my car.

Did Scott have the rear caster tool? What did he set the rear caster to? I live in ma and was thinking of having a more aggressive alignment done to my car for upcoming track days.

rear caster measurement/adjustment still unsolved
This is getting a little crazy for me. The fact that GM makes recommendations for their car that their own dealers will not comply with is itself a major problem.

I am following up on your suggestion about FasTrack. In looking at the printout again and communicating with Scott, he did not adjust or measure the rear caster which seems to be part of the issue with C7 alignments.
