I drive my car pretty hard on track. The only people that pass me on track are typically people with much faster cars, so I either keep pace or very slightly outdrive those with similar cars on track, but that may not mean much because I'm only in the Intermediate run group. I'm sure there are some advanced drivers in the higher run group that would squeeze a second faster lap than myself.
Here's a video for reference. I was experimenting with braking deeper in a couple of the corners the day this video was taken, so I do exercise the brakes hard enough.

So far, yes. My stock 330i rotors were always up to the task even with my stock brakes. As long as you use a good quality track pad and some good fluid, you shouldn't experience much fade. So far with my Wilwood kit, I have experienced zero fade.The rotors are up to the task? How many track days can you do before you need to change them?What pad are you running?
I typically run 2-3 track days per year on average. Some years I'll do 4, but I run the calipers and rotors on the street as well. I swap out the brake pads between events. For the street I use Hawk Performance Ceramic pads purely because they came with the brake kit I bought. Once they wear out, I'll be going back to the EBC Redstuff pads I've used in prior years. For the track, I use PFC01 pads in the front and Hawk DTC60 pads in the rear, which is a configuration that also came with the brake kit I bought. Once those wear out, I will be looking for a suitable PFC line of pad but on all four corners, because OCD.
As far as rotor life goes - I typically get at least a couple of years out of a set of rotors. On average, I have driven 31k miles a year since I've owned my car, so those 31k miles per year include track events and daily driving. Rotors last a long time, as long as the pads you're using aren't too aggressive.
I can't speak to Centric rotors as I've never used them. I'm not sure what my car has now as the rotors were included with my used kit, but they are pretty much new with regards to material. They do need to be cut slightly because I think they're ever so slightly warped. I may just end up replacing them instead, but I haven't made that decision yet. The pads are pretty cheap, but good track pads are still $$. Don't cheap out with pads just because of price if you plan on going to the track, otherwise you'll get brake fade and less enjoyment out of the experience.I have pretty much researched every single option and I think it is definitely the cheapest one to own (cost of ownership which includes cost of consumable was the most important factor for me). Pads are about 40/50% cheaper than the brembo/ST. Rotors are dirt cheap 55$ on amazon for high carbon centric (i have had good experience with them on other platforms) http://www.amazon.com/gp/product/B00...=ATVPDKIKX0DER
