Prepping for the Track, need to input.

I'm thinking about doing some track time and wanted some input on options. My car is a MSport 335i and the thought is to do 3-4 track days a year and a handful of autocross courses.

Wheels - I was planning on running a square setup 18x8 or 8.5 with a ET32-38. I'm hoping this will be slightly cheaper to run since I can rotate tires if needed. Also the front end is really space constrained. I checked spacing and the top of the tire is about 1/2" away and the strut is about the same.

Tires - I was going to run 235/35/18 Hankook RS3. The tires will be 0.5" smaller in diameter which should help with gearing and clearance. The tires will be slightly wider but I should be ok. I've never run the Hankooks before but from what I've read they seemed to be a decent tire. I didn't want a full blown R compound tire because I'm probably going to be driving on them to whatever event I go to close and far. Anyone have experience with these or other aggressive street tires? The input would be appreciated.

TPMS - My Toyota requires me to take it in to the dealer to re-initialize different wheels/sensors. I don't believe I need to do that with the BMW. It seems like I can swap tires and use the reset/recalibrate menu to initialize the different set of wheels. Am I understanding that correctly?

Brakes - I may run the stock pads and rotors but didn't know if they would fade. Does anyone have any experience with the F30 on the track yet? Have you had any issues with fading?

Brake Fluid - I can't find in the owners manual what type of brake fluid they use. I'm thinking that I would be ok if they are using DOT 4 fluid but may want to change to ATE Blue to have a little higher boiling point. Anyone make the switch yet to a higher grade fluid? Are they running DOT 4 or 5?

Thanks for the help,
