Does any one have the GM track specific alignment guide. I'd like to compare it to the number that others have posted in this thread and others. Thanks

It's in the track prep guide you can download from my.chevrolet.com, but here is the relevant page from my 2018 version, I don't think anything in here changed for 2019:

Back to post #58:
Effects of toe-in and toe-out There is one more effect of camber that we haven’t mentioned yet. If you roll a free tire at an angle, it would want to follow an elliptical trajectory instead of a straight line. In other words: an angled tire wants to turn. The force that causes this effect is called camber thrust. This results in a bit more friction, heat and wear, which can be offset by a toe-out adjustment. You can also use a toe-out adjustment to get the slip angles of the front tires in a more optimal spot. So you’d typically run some toe-out on the fronts. https://virtualracingschool.com/acad...ps/camber-toe/

Resurrecting this thread since it seems to have the best discussion about ZLE alignment.
Here is another set of SC3Rs I just took off. Corded inside left front again with the GM recommended alignment settings. I'm considering whether to stick to those alignment settings for my next event or adjust based on people's feedback here. After reading through this thread again, I am wondering if I push too much first session with cold tires resulting in this wear -- I go out on 26 psi. So I think the play here is to try the GM alignment settings again and be more conscious about abusing cold tires. But I'm also open to trying a different alignment. Sounds like some folks have had success with slight negative toe as opposed to the GM recommended slight positive toe.

Heading to the track on Friday. Brand new 3Rs.
Running -3.5 camber and 0.1 positive toe. I'll report my findings. |

He actually told me if im not going out to win a race he said start higher in the PSI like 30-31psi cold and you will get way more life out of the tires. It wont be the most grip but you will get a more track time on the tires. |

I think the consensus has been that the tires will cord on the inside mainly from driving the car too hard before the tires are up to temp (and pressure). Need to bring them up to temp semi-slowly before really hammering on them.

Also to maximize the front life you should rotate left to right every 3-5 sessions. And inside out every 6-8 (1 -2 days).

This I do! Well I rotate side to side. Tire chalk comes in handy for keeping track. I haven't flipped the tire on the rim.

After I started doing that my tires stopped wearing like yours. My best times are always the second run of the day when the tires have cooled slightly from the first run. Remember 2-tenths is not worth the wear and the average driver has more to gain learning the car and track than they will ever gain from running the tires at optimal pressures.
