Bang for the buck, it would be hard to do better than a 1LE.
I assume you are talking about local AutoX events and not Nationals?
- You will never fade the brakes on this car with AutoX. I often have a co-driver in the Summer in Central Florida with no issues.
- Depends on your local region and how good you are. I can beat the C5Z/RE71, the C6Z is a tougher get. I have no problems with the GT350 or the AS 911s. My toughest competition is the ZL1. Same car with 200+ HP. Our margins are in 10th of seconds.
- I occasionally have one of my daughters friends ride in the back. Surprisingly, when you fold the seat flat, I can get in our 12x12 pop-up, two seats, track box, helmets, etc with no issues.
- I would stick with the stock wheel/tire setup for track until you are sure you are as fast as you can go with them. This car is SHOCKINGLY capable on track in completely stock form.
- See 4 above
- Don't know anyone who has tried it, but the 35 height is pretty close to the top of the well. I can't imagine the 40 would fit without mod.
Good luck with your search. I paid more than people are paying now, but I received mine in November. I was in the 1st build week.
