We did the Las Vegas event yesterday (3.29.15). They had a bunch of Jeeps, 300s, Challengers and Charger SRT's for us to drive.
The quality of the event exceeded my expectations. Having done a reasonable amount of autox and tracking on another car I thought not only were the facilities great, but the crew supporting the event were outstanding.
Temps hit 93 degrees, with a slight wind. The crew didn't loose pace with the day and were ensuring everyone got as many runs as they wanted.
There was only one Charger SRT there, and a Charger SRT Bee. Huge difference between the two. The 300's were of the fastest on the road course.
I had a blast. My wife enjoyed it. At the end of the day after autox, drag racing and two sessions of road course time; the instructors took each person out for hot laps. I enjoyed this and so did my wife.
I think it's a great program. Apparently it's been going on for years. There were some 60 people in my group, little larger then normal.
To get really good behind the wheel you'll need more seat time and instruction then they offer. This is a experience, so you're getting in and out of different cars frequently. Seats have been adjusted, cars are different etc. While we touched some high speeds at different runs, tripple digits, I never felt comfortable really pushing the cars. You get two around the road course per session. While the cars are getting a beating, two laps makes it hard to really get into a groove. They do this though because most people are exhausted by mid-day. A few people opted not to run by the afternoon because they were so tired.
The event was very safe. Learned some neat things about the cars, like they're all stock, some had 11k of pure track miles, no issues. They've never had a mechanical issue on these cars. Program has logged over 250k in track miles on SRT products.
My brakes never faded and oil temps peaked at 272f. They felt this was just fine. See that pic below. Also the ESC system never kicked in while driving. They make you keep it on for safety but it never got in my way. While 4400lbs cars they hold much better than they feel they should. You can just keep pushing them and they go where you point them.
If you haven't, sign up. I might even drop the $500 next year to do it again. The value is great. You beat on their car, consume their rubber and they feed you.
But, if you're looking for 20 minutes of track time to really get into a grove. It's not that kind of program. While you can ride along with an instructor it's not heavy on the teaching. The lead-follow will go as fast as you can keep up in the afternoon, so you get the fun you want safely.
