I apologize for the hijack but with the wear you guys are getting maybe you could help me. I would love to worry about heat cycles on the front tires. I did my first HPDE a couple of weeks ago at NCM motorsports park (clockwise track). I was only able to get about 4 hours/230 miles before cording the fronts. -2.7 front 0 toe error to toe in and -2.0 .08 total toe in rear. Rears wore great and ran hot temps pressures of 34lbs with good heat across the tread from inside to out side dropping about 8 degrees each from inside to middle to outside. I ended up with front hot temps of 37.5 to get the best heat gradient. The left front dropped about 4-5 degrees each from inside to middle to outside. The right front had temp drops ranging from 15 to 20 degrees at each point. After one day, about 3 hours of track time, the inside edge of the right front was severely over worn and the inside edge of the left front was wearing great. I rotated the wheels and was down to the cords on both front tires at the end of two 30 minute sessions the next day
My sessions ranged from 30min to 1hr long.
I am wondering if shorter sessions are helping the inside edge hold up.
Any thoughts?
I am also thinking about running -2.3 camber on the right front when on a clockwise tracks and vise versa to get better heat gradient across the inside front tire.
Has anyone done this?
I would love to see three track days out of the GY3R. I have only run NT01 on my corvette in the past and they never seem to cycle out.
I appreciate the help and here is a video of some laps.

update: Checked the alignment yesterday and the toe shifted toe out to .27* total toe. That would explain why the inside edge of the inside tire was getting scrubbed off. Hopefully the suspension will be settled now and not change during the next track day.
I would still like to know if anyone has ran different camber for the front for different tracks to get some longer life. Thanks.
