Keith Verges - Dallas

My very early data from COTA is consistent with Sam's, but I did take pyrometer data. Camber -2.2 F, -2.0 rear. Hot pressures for best lap times I could run were 33 all around. With those pressures the center rear was hottest by about 5 deg, front was hottest inside with a spread of less than 20 deg, and conventional wisdom says you want inside 20 deg hotter than out. My plan is to go to -2.6 F and -2.3 rear. My bars are already set full stiff rear full soft front. I had tried to go down on pressure but picked up a nail for some excitement and was unable to complete 3d session Sunday and tire was trashed. I think I want 32 F and 31 R hot.

Best lap in 50 deg ambient was 2:24.2, ran several 24s then times dropped off, perhaps due to excessive pressure.

From just look of tires I'd be shocked to get 25 heat cycles. I predict half that.

My notes from a couple of sessions attached.
