I don't know where your getting this PPK idea from. No one on this thread has used that stuff on the track.
on a lighter note: WOOHOOO! 1,000th post! I'm a major now!
What if we just get the secondary radiator for $400, would that be worth it compared to an aftermarket radiator for $1k? Of course, I'd be interested in HP Autowerk's radiator but it's not released yet. Also, which 335i (HP Autowerk vs. ER) had better overall cooling and better track times?
