Time attack session time 17:00-17:30. Nice cold weather conditions at 8 Degree Celsius although a bit windy.
Because the Front Left and Rear Left tires work the hardest I set the initial cold pressures asymmetrically as bellow:
1.7 Bar (24.7 Psi) |FL|---------|FR| 1.9 Bar (27.6 Psi)
1.8 Bar (26.1 Psi) |RL|---------|RR| 1.9 Bar (27.6 Psi)
Estimated peak tire pressure during the race was 2.4 Bar (34.8 Psi), after the session a measurement reading was 2.2 Bar (31.9 Psi) for the Front Left tire, 2.1 Bar (30.5Psi) for the others.This paid off hugely because the car had much more grip in the corners. Much more stable rear in the fast right turner as well.
And if it wasn't for that slow Clio driver I could've achieved a lap time 2:37,xx s. I lost almost one full second behind his ass.
Anyway the tires are pretty much done, the're good for just one session.
Another chapter is the brakes. They didn't perform as well. They basically faded right in the beginning. Too mushy, too long pedal stroke. This made me screw up many heel-toe downshifts.
At this point I'm pretty sure the Ferodo DS2500 brake pads are not suited for hard racing with many consecutive hot laps and hard braking.
The pads got glazed too much. On top of that I somehow managed to wear down 2-3mm of the initial thickness. And they are just over a month on my car!!!
I don't know if there are brake pads for ITR that could cope with such abuse and still be road legal? I suppose the only way to solve this issue is to upgrade the front brakes to Spoon Monoblocks with 300mm brake discs and larger rims.
I have to put the trackdays on hold until the brake issue is solved.
