First of all congratulations ! I to have been waiting patiently for mine to arrive as well, ordered in Sept and I am hoping it won't be long now. What I have found is every time you get looking though this forum the more options you will find available that you may not have known about and you keep adding to your want list, lol. My only regret is not taken the trip down to see Fran and nailed down exactly what I wanted right at the get go it would have save a ton of time and Fran wouldn't cringe when he see's my name on the phone LOL. But from I have seen and read if you looking for true bad ass car this is the best bang for the buck.
as for your tire or tyre delema lol,
No matter what, your are going to want a very good Z rated or higher I have had my tires delaminate at 120 mph made hell of a mess, and as sticky as you can get with that kind of HP or you won't be driving the car, it will be driving car you.
You may have to change them often, but its not worth taking any chances.
Tires are the most important thing you will buy for your car.
Learn't that one the hard way didn't cost me my car just a pair of underwear.
one more big tip watch the air pressure 10 lbs differance in soft tires can cost you a car. You should have seen that one, My friend Gord will never be the same lol.
