Burnt up my Brembos in one session.
Honestly, here's my conclusion on the brakes. The discoloration of the calipers is a little odd given the circumstances. A little discoloration was expected but not as much as what occured, however, the brakes never did fade and the fluid never boiled. I think the main problem was the pads. Being a street/track pad, I think I just got those too hot on the front and it caused uneven deposits which then caused the vibration that made me think the rotors were warped. So in the end, I think it was more the pads then the brakes themselves.

If you don't go with a BBK you may want to talk with Martin from Girodisc. He used to be a Porsche engineer and is the brake expert. His two piece rotors and titanium shims might be another possible solution for you.

Thats one of the causes, but I followed the manufacturers procedures and they worked fine until they heated up. I think I just got the pads too hot. I don't think I would have a problem with the DS3000. I think I am just going to get some cooling ducts and maybe the titanium shims and Girodisc rotors like nicka117 suggested. Then once I get some better suspension in there that should help transfer less weight towards the front of the car.
Sounds like you're ready to step up to some real track pads like the Performance Friction PFC-01 or 97.

"Ferodo DS2500 is a club race pad that can be used on the street and for light track use."

cfdfireman1 & ryan0 - Absolutely, I just didn't think the car had it in it to overdrive those DS2500s since its basically slower than stock with the handicap of the tires. Thats the thing that suprised me. I knew that in a modified EVO the OEM Brembos wouldn't stand a chance without at least a lot of cooling and full track pads.
The calipers being black is normal, I am yet to see an Evo that is properly driven without at least a very very dark red color.
The warping is likely due to improper cool down, I know lots of Evo owners who track their Evo and end up with horribly warped rotors because of that, mine get so hot they smoke and I'm yet to warp one because I spend about 10 minutes driving the car around slowly after a session and then I NEVER put the parking brake on. If you did all that as well, then something more serious is going on. Especially if you're using DS2500s since I use much grippier track-only pads like DTC-70s, DS3000s etc.
Now the brake piston dust boots are another story, mine got toasted pretty fast, but the concensus on the forum seems to be that they're totally unimportant.
