Z51 half-way track alignment
Randy Pobst tested my z51 at VIR with 2 deg neg camber up front and neg 1.5 deg in back. Cost me a ton to bring you this result but here it is 😆. If you have seen the motortrend clip or aware of the track performance on both alignments, TLDR skip to 10:00 mark.

Loved the video thanks! I’m getting a new alignment next week and was struggling to decide on this.
Before my last track event my dealer refused to do this so I ended up at the aggressive bound of street (-1.1) and it probably contributed to my tires barely surviving one track weekend. Found someone else who will.

I run my car with the GM track alignment except zero tow front and back. No issues with tire wear being a dual use car. Have about 20 events and numerous sessions with this setup. The biggest benefit for me was going to a 200TW tire 285 front and 335 back. Dramatically reduced understeer.

Wow! When Randy agreed with your idea, you HAD to be thrilled!
Randy said you are running Cup2 tires. What size tires? Was this your first event on those tires and how many miles do you have on them?
I am doing Summit Point Main next month and will set up my car just as you have done.
Thanks for posting!
