Pulled the trigger yesterday on a 6mt coupe. This will be part daily driver, part track car (about 1 trip a month). I was looking at e90 m3's and 335s as well as e36 m3s and bought this. Go figure, am I out of my mind? A few questions...

Any known common issues running on the track? Things to look out for?

Tires- do you guys go down to 18's non rft?
Suspension- what upgrades provide the most bang for the buck?
Intake upgrades?
I will probably eventually go with a Cobb or other tuning device but a bit down the road.

Any help would be appreciated. I attached a pic.
