As it was very cold I started with 1.9 bar front and 1.8 rear cold, car was on Kumho KU 15 (feels like semi-slick with more cuts). After temperature had come into the tyres, it went up to 2.5 bar all round, which is def. too much. I went two tenth back and pressures held at 2.25 bar, which was perfect. The set-up is not a race set-up, it´s a compromise with little camber front, almost no camber rear.
We have questions about track day tyre pressures every now and then, so even if it is as cold as it was on Friday and even with a street set-up, I would start with 1.7 bar front and 1.6 bar rear cold. Two much pressure -especially in the rear tyres- will cause a vicious oversteer. So pressures hot shouldn´t be higher than 2.3 bar all round.
Slicks is a different story.
Maybe that helps,
