Brake question for you track junkies...
What pads are you using? I'm guessing that the stock pads are going to be toast after a couple laps, any suggestions (not ready to swap out to the StopTechs yet...maybe in a couple months...)
I'm going to flush out the system with Ate SuperBlue (lots of good experience with it), but need some better pads...don't care how dirty they are, just don't want the really corrosive Hawk Blue dust, if possible...
Thanks!

pads and fluid won't help at all . . .
the brakes are just not up to the task of track driving, unless you are talking an oval! lol 
Brakes cannot stand up to repeated slowing from speed. They overheat, fade and you end up losing your brakes. I went straight at the end of the Lime Rock straightaway at about 110 and went off at turn one at Watkins Glen into the gravel trap at over 115! The car was not hurt in either incident, but that is the reason I got my AP Racing setup before hitting the track at Summit Point.
If you are just going to be driving at 5/10th then the stock setup should work just fine, but one you get out there you will want to begin to push the car and yourself. Unfortunately the brakes are not up to what the car is capable of.

Hmmm...
I find that kind of tough to believe - I've pushed my old e-36 BMW pretty hard at Sebring with nothing more than a set of Hawk Blue pads and superblue fluid, lap after lap with no fade. That car was not a whole lot slower than the TT, plus it's got substantially smaller brakes...

At all, Larry? Won't 'upgraded' pads allow for higher temps before they fade?
This would delay the fade, and allow more braking before you lose brakes, but they would still fade as continue to use them.
How many laps before the Ninety got you at the Glen? It got Dale Jarrett twice last weekend!
Of course a Cup car is going a LOT faster, but it weighs only a bit more than a TTR!

Mintex C-tech or EBC Red Stuff pads w/motul 600 may help initially
I was able to get by with upgraded pads and fluid for several track events. Larry is correct though that eventually you will be pushing the car beyond the capabilities of the upgraded pads. There is also one track in particular that I have run on that has been notoriousd for destroying brakes - Texas Motor Speedway. Your success will depend mostly on how "brake friendly" the track is setup.
One thing you might try is the new Zimmerman rotors with a true track pad on the front like EBC Yellow stuff. I was planning on this setup but took the Stop Tech plunge!
Good luck!

I went off at lap 4, but I had to keep extending my braking zone further and further
up the track. I was not able to even come close to the braking zone I should have been using. I had to lift before the markers and brake before the markers in order to slow down enough to be able to make that turn. We are not even talking a very high speed either.
If you go back to some of the magazine reviews that did a comparison with other cars and the TT, they were leaving the TT on the side of the track for its brakes to cool down after fading during 60-0 stops.
Pads are not the problem. I tried different pads and went off with those as well. I think it is a combination of not enough caliper and the rotors can't disipate the heat fast enough.

how do you like the stop techs?
Any problems with fade? They seem to be the most reasonably priced of the big brake setups (down to $1795 right now!)...what do replacement rotors cost? How about pads?

I agree that there's not enough rotor to absorb/disipate the tremendous heat...
C5 has much larger brakes, but they aren't adequate for track usage either. Of course, the manufacturers are not designining cars like the TT or even the C5 for track usage. The design criteria is maybe one stop from max speed or a few stops back to back at max g from highway speeds.
0-60 to 0 back to back for more than a few times is also pushing the design criteria. You could easily do more than one 0-60-0 per minute...maybe 2 per minute.
FWIW, I'm surprised you got 3 laps at the Glen before you lost braking. I don't think a stock C5 (admittedly faster) could do 3 hot laps at one time.
Few street-based race cars can maximum brake every lap. IMO, very few race drivers use maximum braking in a road race except in qualifying or trying to pass under braking. Cup cars certainly don't. Who knows even if F1 does.
Thanks for the info.

You're right about the C5
I got rid of my 2000 coupe when I got the TT. The C5 with stock pads was into full fade mode after a lap or two at Sebring. With a set of race pads (Carbotech Panther Plus) I could run almost an hour at Homestead with no appreciable fade. The tires (not run-flats) would be all greasy and goey well before the brakes gave out. Rotors turned blue with heat, too...
