Matt J,
Get those 13-YO tires off your 911 NOW. I’ll come and help you take them to the shredder.
A few years ago, we had a ‘play day’ at PPIR (
(with these cars) and someone with ‘like new’ similar age tires made 1˝ laps before two exploded (almost simultaneously).
Tim,
Matt J.’s configuration would be well suited for your SC coupe.
Every car/driver/track is somewhat different.
There is no ‘one right’ solution.
Everything is an engineering compromise.
Pick a well-balanced (and widely used - peer reviewed) configuration.
Test and then re-modify to get ‘best possible’ for
you (this is a forever ongoing process).
… just don’t try and out-corner a Lotus with 500 Kg less mass and a 10 cm lower CG.
For grins, rent a ride in a very lightweight (<500 Kg) and low-CG formula car or Sports Racer.
Try some 125 cc shifter karts with fresh tires.
You will see.
Best,
Grady
