I am having the hardest time getting heat in my rear tyres on FWD cars. Lower tyres pressure works, but then I end up having the outer and inner of the tyre warmer than the inside (not enough pressure). Is there anything else that would help here?
I use usually the highest -6,0 camber at the back, try it, maybe helps a bit, but as Sander said you cant do much about it. Set the pressure that the middle is between inner andouter, and absolute value is as it is.
on some tracks i find that you can get away with overinflating but it can be hard to find the limit where it affects the car. also depends on race length
