If you check your tyre temps the centre will allways be hotter no matter what camber or tyre pressures your running so this means your mainly using just the centre of the tyre , i use trackmap and this shows that the tyres are always overpressure when up to temp .
If you watch the tyres on a video you will see they are soft and underinflated which can cause the centre to run hot , but, if you raise the pressures all that happens is that you loose grip and run hotter still , its this temp/ pressure imbalance that ISI need to get sorted , when they do we should have more grip and be able to setup the cars properly and easily , the current way we set these cars up will not then work , in the 60s these cars ran on crossply tyres which had mega stiff sidewalls so if you added camber you lifted part of the tyre off the track and lost grip, on todays radial tyres the sidewall flexes and allows the tyre to grip across its width , if you check video of these cars you will see they run little or no camber but modern cars can run huge amounts of camber .
Just a little observation to this , check out the top picture of G's new skin and look at the tyres on both cars , g has lower pressure (sidewalls are bulging) and little camber so his contact patch is almost full width on each wheel , the car next to him has high pressure (no Bulge) and bigger camber , look how little of the tyre is in contact with the road .
Understeer - is when you hit the wall with the front of the car
Oversteer - is when you hit the wall with the back of the car
Horsepower - is how fast you hit the wall
Torque - is how far you move the wall when you hit it
