I spoke to Randy yesterday here at Sebring for maybe 10 minutes as he was under the Autoquest tent coaching a driver.
He remembers the .1RS as twitchy and I disagree.
Then I took a lizard .2 RS on track yest day.
The new one was setup differently and the front end had big grip, bound up even, making the car... twitchy, slow and hard to drive.
So, it’s all in the setup. It will, again take testing to sort out all the setup options, and then again with different spring rates and wheel sizes...
Between the sway bars, downforce, rake, camber and toe the adjustments are massive. That’s before modifications.
i will say that the .2RS pull like a freight train, I expected just hype because 4.0 is 4.0, but I was wrong, the throttle and/or engine is so much punchier and torque is up more then the numbers suggest. I’d almost want a more adjustable throttle input, but I’m sure it’s fine when I recalibrate.
More testing today :-)

I'll be down there next Sunday with Chin.

This.
And it's true of all track cars. It takes subtle adjustments made incrementally with more testing in-between. Adjust, run, discuss, adjust again. Rinse/repeat until the driver is happy. The range of behavior on my Radical is amazing - when improperly adjusted it behaves terribly.

As a prior owner of .1 GT3 and .1 GT3RS I would agree with Peter that the handling of both cars were excellent
when set up properly. Any Tracked Car can feel "twitchy" or display understeer or oversteer with a bad set-up.
And I also noticed the unexpectedly large increase in low to mid-range Torque on the newest .2 Engines.
Very few new cars come from the factory set-up optimized for track use.

Not even trying in someone else’s car with only a 3point seat belt I turned 2:15’s in a .2RS.
i thought I was turning 2:18’s!!
all in all I think the torque and downforce are good for .5-1sec a lap once we get it setup.
Found some improvements yesterday!
my car with mods is a 2:12x at Sebring, the new one TBD!

2:15 is about 2 secs faster than a well setup 991.1 GT3 RS on mpsc2 at Sebring.
