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

Grady, the new Potenza RE11s are supposed to be in on Thursday. Putting around town is all that this car will do until it gets new tires.
