well finally got out to a T&T last night .
5 passes . It was warm low 90s down to low 80s with humidity in the teens .
Was hard to get car cool , especially with the 30 minute traffic jam on the freeway on way in . was around 190deg engine most passes
DA was 2840 down to 2250 between 6.17PM and 9.12PM
Any hoo .
First 2 passes was like oh my god , very slow sixty /et( 1.48/10.48) but mph was normal at 1/8 and 1/4 . OK new tyres .
PSI started @ 19 1/4 then 20 psi , shock settings as per normal
3rd pass 21psi and bigger burnout . 1.46/10.39/128.89 . That's better
4th pass 22psi same burnout . 1.46/10.40/128.37 . Tyre face looked better across
5th pass 22psi same burnout . 1.45/10.38/128.47 . Tyre face looks about right .
Track championship round next weekend .
Tyre feels good , I hope it will come in a little more , car has been 1.42/43.
I know I can dial to this .
Thanks for all the feedback/replies .
