Try to get the tire temps on the right hand side equal. If the front is
hotter, soften the front or stiffen the rear roll bar. Don't worry about
the handling too much, get the tire temps right and the handling will come.
Driving style is important too. Don't slide the car like you would on a
roadcourse, or your tires will overheat rediculously. If smoke starts
pouring off your tires you'll just have to slow down.
That's what worked for me, anyway. Good luck!
