This past weekend I took my R to the track for the first time and I wanted to report my impressions. I also noticed that there were no threads about this topic so I hope that this will be used in the future to discuss about track days.
If you're reading this and you plan on tracking your Shelby: The owner's manual mentions 28 psi as the optimal tire pressure for racing for both R and non-R models. I personally had much better results with 26 psi and outside temperature was never higher than 72. I have an R model with Cup 2s so I'm not sure if it applies to GT350s with Super Sport's. Just something to keep in mind.
If I had to summarize the experience in one word I simply put it as: insane. The car has so much lateral grip that I struggled to convince my instincts to keep the foot off the break during some turns. The balance and weight transfers are flawless and it responds to throttle inputs instantaneously and without offsetting the balance, the only other car that I remember being so sharp it's a 911 GT3 that I've driven last year. Breaking power is something from another world. I recommend trail breaking through corners due to, again, the composure of the chassis under stress. I beat my personal best by almost 6 seconds without even pushing too hard. I could have definitely pushed it a lot more but I simply didn't have the guts to do it being the first track day with this car.
The thing that struck me the most was that this is a big, heavy car. However it feels so nimble on its feet and it feels like it gets lighter and smaller as you go faster. Even in technical sections where power doesn't really count I was going faster than many Lotus and GT4s.
Below is a video shot with my GoPro. Quality is not great, but it gives an idea of how she does.

The only sad thing about all of this is that I drove home thinking "I have to sell this car". After a day at the track you realize that this car can only be really enjoyed on a track. You can't really use it in the city, and it is so well done that in the canyons/back roads it's almost boring. On the other hand, the tires on the R simply melt away when racing. I did 3 sessions out of 4 and I doubt I'll be able to do more than 2 sessions the next time I go to the track with the same set of tires. Between labor on the carbon fiber wheels and the cost of the custom Cup 2s you're looking at more than 3 grand for a tire change. So between tires, track day insurance and other misc expenses each time you take take it to track you're burning ~$2000. Don't get me wrong, these are nice problems to have, but don't be surprised if you'll see me put it for sale soon.
