I'm not Mike... but I'd advise against going with super wide tires like that and stock power. I went from stock tires to 245 RE-71Rs and though my corner exit speed is ~5-10mph faster than before my end of straight speed is only 1-2mph faster.
Stock brakes simply won't hold up very well without ducting, no matter what you do with pads. I'd consider myself similar to your level of driving and I was killing XP10s on stock tires and killing XP12s with the RE-71Rs. Just starting to fade them, but I was smearing the pad on the rotors and generally wasting a lot of money.
You'll likely want camber plates and rear lower control arms, you can't get a decent track alignment out of the stock stuff. The rear camber isn't adjustable at all... If you get lowering springs, you'll likely not need the rear lower control arms, the camber falls into a decent range then and less hassle doing alignments and such.
Otherwise, the car is very enjoyable. I've had no reliability issues and I beat the crap out of my car at autocross and on the track and drive it to work the next day
