Has anyone done any research on break pads that are avaliable for the Sti Brembos? Will be going to the track soon and want to switch out my pads for the day. My brother lost his breaks after three laps in his Sti. I will also be upgrading the lines and fluid at the same time. Any suggestions?

 

http://www.cobbtuning.com/ they have some new pads for the STi

 

Personally, I have found the stock STi system to be adequate, but others have not. First, put good fluid in, like Motul 600 RBF. I have gone through 4 track days with just this and I've been fine with no fade (1/2 hour sessions) -- on the RE070s, not R compounds. As I said, some people have issues, so it depends on how aggressive/fast you are together with your braking style. Being on the brakes for a long period of time is supposed to be worse than a shorter period with harder pressure. It is problematic when you're stuck behind a really big car like a BMW 750 that has to brake really early and long, so you kind of end up doing the same thing.

I've heard good things about the Carbotech XP 1109 and the Porterfield R4 pads. The XP's are newer than the Panther Plus and are more of a track-only pad. The XP's temperature range is a lot higher than the Blue's (1400F vs. 1000F). I can't find a temperature range for the R4's, but the R4-S goes to 1100 so I would expect the R4 to be higher. This assumes that the companies all mean the same thing when they quite temperatures, which is probably optimistic. For street/autocross use the Carbotech Bobcat or Porterfield R4S would be good -- they are not track pads however (some people report success with the R4S, others do not).
