Same with my ex rs cup diffusor and wing at the max never more than 280 with that spec
the gt2 is so secure at that speed, you feel the aero so hard and the german autobhan where i did it is in bad condition (small bump)

Salut Seb,
On track i targeted 2.0² with starting 1.8 . Any comment on that ? the tire pressure is quite a science.
Also the working window of these tires in quite strict temperature/pressure wise( Also depending of tracks.
I have finished the OEM dunlop and now will switch to Pirelli.
Regarding the tires pressure while cold i think no matter what pressure you put the car have so much power that the rear want to lead. People are happy to call her widowmaker i guess we have to deal with that no matter what is the pressure.
For the temperature i have the same stuff here. I have been super carefull with the cool downs on track and engine witch off before parking for the turbos.
I will be in France, Castellet track for the start of the season 1st and 2nd of june if french rennlister are around !

It is a problem when driving shorter sessions. You don't want to pit to lower the pressure.
But it still might be a good idea to do like Seb mentioned. Not too low and reduce when heat has come to the tire.
On the Ring maybe .1 or .2 bars extra is a good idea because of the high speeds and the big compressions.
I'm not sure if this was a result of hard driving on too low pressure or if it was just bad luck:

I'd be careful going out on too low pressure.

3.0 bar cold is crazy.
and even more crazy for those people who follow the rules, never take care about tire pressure during driving and amusingly those guys normally have the heaviest right foot and slowest countersteer hands.
but for sure P have also a reason for this... ?
keep ´em comming seb!
and my A1 one was also xpel wrapped. you could double wrap the critical sections like the rear fender parts / in front of the rear wheels. thank you EST.
each solid black paint - is a pain in the **** if scratched or dirty - but as long its clean its the most worship-able noncolor of them all.
