Chevy Dealer couldn't do ZL1 "Track Alignment"

[Macaro]

Hello,

So I took my new ZL1 (1700 miles) into the Chevy dealer for it's first service. I had them do two optional things, a brake fluid flush with Motul 600 and a "track alignment" as per the video linked at the bottom from Chevrolet. They hemmed and hawed a bit about me giving them alignment specs but agreed to do it albeit for more $ than a standard alignment. When I picked up they told me that the couldn't quite get to -1.5 degrees and had the fronts at between -1.3 to -1.4 degrees. I don't really care about the difference except that I found it odd that they couldn't get to the spec that Chevy itself put out in the video. When I thought about that I emailed to ask why they couldn't match the specs exactly and the answer I got back was:

"The reason we could only get that front adjustment is because of your front struts. There's a slot that allows an adjustment and we're to the max. Aftermarket places may be able to grind the slot bigger to allow more adjustment or you may need aftermarket struts."

Does this make sense? Have others out there found this to be true with the ZL1?

I don't know about ZL1s but my stock front suspension SS is at -2.1 without any elongating.

Get a set of camber plates.

Both our V6 and our 1LE have been able to get -1.9 to -2* of front camber

So does this mean my dealer is a bozo?

I had a "performance" shop tell me they couldn't get more than -1.3, -1.4 on my ZL1. I marked the hub to mark the alignment prior to installing camber plates and I got another 1/8". I'm not sure what that's worth in additional negative camber but I was surprised I was able to get more myself.

I never use GM for track alignments, I just take my specs to a quality 4 wheel alignment shop in town.

Yep, find a performance chassis shop. I use one local to me and they do awesome work and will do whatever I want, as long as the stock equipment is able to do it of course.

The guy that usually works on my car actually drives and co-owns a chump car also.
