Completely different car, but in my Focus, I ran my Konis at 3/4 front, and a smidge past 3/4 in the back. At higher speeds, too much rotation is bad. I would go more conservatively, and then adjust from there.

(Last year at VIR, for my first track event, I had my rears up too high. I pitted after 2 laps because it was too squairrly. Once I toned it down, it was great)

As for tire pressures, start a little lower. You'll be on track for 20-30 minutes at a time, and your tires will build up a little more pressure than they do at autocross. I think I was running like 36-37psi cold up front in my Azenis, and coming off of track, they were up to around 45.

Which circuit at VIR are you running?
