F30 335i M Sport Required Upgrades for HPDE Events

Hi everyone,

I recently purchased a 2014 335i M Sport and I'm looking to get into some track days at Sebring and want to know what suspension and brake upgrades I should be looking at to enjoy my time on the track.

I just installed Michelin PS4's and have the OEM M sport brakes and suspension (non-adaptive to my knowledge). Also I have an 8AT, does anyone track their auto F30? Any issues with overheating/heatsoak? I have an AA intercooler that is going on before any track time along with CP and DP and Stage 2 tune.

I should add that I have some track days under my belt in my previous cars: E92 335i (Sebring, Summit Point) and 981 Cayman S (Roebling Rd) but not a pro by any means. Thanks for the guidance.

High-temp brake fluid should be all you need, you already got good tires. The 335i is quite capable. If you fade the brakes then the next upgrade would be pads, but OEM pads should hold up fine. GL!

+1 on the brake fluid. I'm a big fan of the Motive bleeders, they work incredibly well.

Have fun and stay hydrated

Post up some pics/vids afterwards

What brake fluid would you recommend and should I go ahead and install stainless steel lines at the same time?

You can pick up something worthwhile at AutoZone. Limfac for the m sport is the pads

Ask a BMW-specific shop that works on race cars what they recommend. Turner or VAC are two shops. But basic high-temperature fluid should be fine.

It's not like your car won't work on-track with the standard BMW brake fluid. It just won't have the temperature threshold; the limitations of the brakes wouldn't be as high. E.g. you might have to take a cool-down lap now and then to let the brakes cool off.

I used mostly Motul 660 fluid on my old E90 M3 for CCA HPDEs and worked well. Car always ran on Michelin PS2 or PSS, whichever was newest available at the time, and stock pads first, then PFC Z-rated pads after that. I've not tracked my F30 340i/6MT. Have fun!

Bumping an old thread here but Iíve since installed a set of coilovers and looking to swap out my brake fluid. Does anyone know how much brake fluid is needed to flush the full system? Also any recommendations on bleeder systems to make the job easy? Thinking about picking this up https://www.ecstuning.com/b-schwaben.../007237sch01a/

I used 3 bottles of Motul RBF600 in my recent brake fluid flush and that seemed to be the right amount. I also have that Schwaben brake bleeder and it worked fantastic, better than the Motive one a friend of mine has IMHO.

I used Motul 600 and Powerstop Sport pads this weekend at the track and they were great. Using the 4/2 pot msport brakes.

I bought whatever the best pads and rotors are from BMW and they worked extremely well. No brake fade at all at Road America.

Expensive though.

I wouldn't bother switching if you have some pad left though
