Ride height 5mmF, 6mmR, raise it up more if the chassis is dragging over bumps
Lower if it's a smooth track
Adding rear droop should give the car more corner entry speed, at the expense of stability

Softer front springs, with at least 2mm droop should help

Just some basics for tuning...

I've yet to see rubber tires match corner speed of foam tires
That will be an uphill battle
