Hi guys,

I'm coming from a 350z setup based in California, moved to New York area and now have a 2008 335i 6AT for family/weekend warrior stuff. I only have 2 HPDE events at Willow Springs on the west coast under my belt. I haven't done much cooling mods previously since I've only tracked during the Spring or Fall seasons in the 350z, but I keep seeing threads about limp mode on various forums for the N54 platform and have been closing monitoring this thread https://*********************/thread...rack-use.4352/

However, the users I see within that thread look like they track consistently year-round or may be too advanced for my skill level. What would be a realistic** cooling setup for annual 2 to 3 track events with the use case below? I want to at least complete continuous (3) to (4) 20 min sessions throughout the day. Appreciate any advice and thank you guys beforehand.

Car: 2008 335i
Transmission: 6AT
Track Tires: Performance Street Tires, probably summer type, brand interchangeable, probably won't be able to afford R compound consumables even if my skill level requires it someday
Aero: Stock
Brakes: Upgraded pads and rotors w/ DOT4, no goal for front BBK setup as of now. Might upgrade for looks, but for consistent track/canyon cruising consumables might be too high for me
Power Goals: 350whp - 380whp via FBO, willing to de-tune further
Gas: 93 pump gas
Suspension: Digressive coilovers + M3 arms
Drivetrain: 1.5 LSD
Tuning: MHD + XHP
Driver Mod: Non-competitive beginner, goal is to be in whatever equivalent intermediate class for fun. If I ever get to an advanced level (highly unlikely), the hobby would get too expensive from a consumables perspective and the cost of my own time for DIY so I'm very realistic here.

Track that I'm interested in: Watkins Glen International
Fall Season High Temp: 70F - 80F
Fall Humidity: 65% to 80%

I see that people have recommended an auxiliary radiator, secondary oil cooler, and transmission coolers. Would these off the shelf hardware options be viable for my use, assuming the software is tailored?
A. Scenario 1
1) 335IS Auxiliary Radiator w/ OEM Primary Radiator - would this be enough to cool my trans and coolant?
2) Hard Motorsports or FTP Motorsports secondary oil cooler, I have a stock oil cooler

B. Scenario 2
1) CSF Primary Radiator for Automatic
2) BMS Trans Cooler
3) Secondary oil cooler

Again, thank you guys for any input.
