Tire wear pattern Options

Check out the pattern of the rubber on my RA1's. I did DE's at VIR, Watkins Glen and Summit point since flipping them mid season, so have about 400 miles on track, 15 heat cycles since flipping. These are the fronts....the rears are much more uniform without a buildup of "worms". The buildup is on the inside edges. I'm guessing that it's indicating that I need more camber but I'm maxed out already. Ideas?
BTW, total mileage on track with these tires since new in March is about 1700 with 61 heat cycles & no sign of cording anywhere yet.

All that pickup (buildup) on the inside of the tire is from the cool down lap.
With a lot of negative camber the outside edge of the tire hardly touches the road when you're going slowly around corners, so only the inside half gets the marbles smeared onto it.

In addition to the wear bars in the circumferential grooves there's a series of tread depth holes on the tread surface.
You need to compare the depth of the inside ones vs the outside ones to get an accurate measure of tire wear across the surface.

I would back off to 2 deg. negative at the front and 2.4 deg. at the rear.
