I will let you know for sure. What speeds were you getting on at the back straight? I am guessing mid 160. Also, at what point where you shifting at? I am guessing you were waiting for the shift lights to come on during the race mode.
Were you able to go through the kink on the front straight at wide open throttle or did you have to left off a bit?
One of the things I worry about is braking hard going 160 or so with 315’s in the rear, but from what I have heard..... the factory brakes are pretty substantial.
I have had my 570S on Track at VIR. Car was bone stock.
I am not sure how to qualify my skill level- I have done some amateur racing in an Ariel Atom and a couple BMW sedans. I had the lap record at VIR in both the Atom and one of my BMWs. I have probably 75 track days racing and other stuff at VIR.
The brakes in the 570 need nothing beyond stock.
The stability of the car braking at speed is enough to keep you wide awake- I’ll call it “lively.”
I would start with cold pressures from 24-25 psi (super annoying alarms going off until temps come up after 2-3 laps - kill the alarms with left stalk while going down the straight) with the goal of getting 29-30 hot. If your pressure gets into 32-33 range it is a bit too lose.
I was blitzing past 178/179 mph cresting the hill 2/3 of the way down the back straight- keep the throttle planted until after the crest or the rear will get too light. I coasted into braking zone after hill, not sure what I would have been doing if I kept it pinned - 180+?
I took the front straight kink wide open once- regretted it, didn’t do it again- the rear just does not have enough downforce at 150+.
I bought a 600 LT, breaking it in, can’t wait for VIR. Love that track.
