Brakes are honestly one of this cars biggest weaknesses on the track. However, I'm not inclined to make the upgrade on pads/rotors because of warranty and maintenance preservation.
Another huge weakness I haven't addressed yet is the suspension. This car bounces and rolls all over the place and grip/confidence/stability suffers as a result. I will likely make an upgrade to Coilovers, but not the $3500 options. I'm looking at BC racing and there is a local distributor in the Atlanta area that I'm talking to who knows a lot about setting these up. I will say that "learning" what to do with all this body roll has been a good learning experience. I have experienced understeer and oversteer and knowing when you can apply throttle to steer the car is something I'm still learning (and trusting).
I will update again after installing coilovers.

If you're worried about warranty, just swap track pads before/after each event. Stock BMW brakes were not meant to handle repeated heavy braking. I view the ability to avoid fade more of a safety issue than performance.
Sorry but I'll take oem sport suspension over BC any day. And you don't need to splurge $3500, there are many options that price in between BC and JRZ/Motons that are much more trackworthy than BC.
