I'm a little scared though, after reading about all the heat related limp modes. I may pull the trigger on the Stett Stage 2 Oil Cooler with the 180F T-stat or the ER Dual Oil Coolers just to protect my investment in the track day / weekend / time off from work. Plus, I hope I'll keep getting better and need the cooling sooner than later. Thoughts on oil cooler mods prior to my first track event?

That said, awesome info contained in this thread! Because of you guys I now have distilled water and 3 bottles of Motul Mocool (DIY link) and Motul 600 ready to go into my car tomorrow.

Also, I'll be removing and cleaning my vanos solenoids as proactive maintenance. - DIY link

Not necessarily track mods, but I have some other fresh fluids to address tomorrow:
Royal Purple 5W-30 - 7 Quarts - DIY link
Royal Purple 01300 Max Gear 75W-90 High Performance Synthetic Automotive Gear Oil - 2 Quarts - DIY link
Royal Purple 01512 Synchromax High Performance Synthetic Manual Transmission Fluid - 2 Quarts - DIY link
CHF 11S Power Steering Fluid - DIY link

E90Post is awesome!

as you have a 6MT you'll have far less heat induced problems. I've driven my car in summer heat on a tight course (= nightmare for 6AT coolant temps) where it would overheat within 2 or 3 laps, despite massive cooling upgrades. Same day I drove a friends 6MT for 25 minutes session without issues. He only had upgraded his stock OC with a Setrab core.

So in your place I would get the ER Sports upgrade, maybe even the dual competition package if you want to be safe in any condition.
