Check out my video from an HPDE event I did. It was at Homestead Speedway and through Chin Motorsports. The event was awesome and very well organized. Lots of run time, like almost 1.5 hrs of track time! I ended up boiling the brake fluid near the end on my Brembo 4 Pistons with EBC slotted discs and yellow stuff pads. They held up great with no fade until the DOT3 fluid boiled which I think wouldn't have happened if I had DOT4. Heres the video link: That was my second HPDE and I've been to a couple auto crosses as well.
