no-nonesense track brake setup

I have used PFC-11 since the PFC-01 compound became limited in most pad shapes. My experience is that your view on cold bite is incorrect.

Your view is also inconsistent with Performance Friction's own test data and statements re: cold vs hot effectiveness..

I do think you sort of misunderstood me. Of course there's a difference in bite cold vs warm but when you can get in the car and drive normally then I don't think cold bite is an issue.

This is the only reason I pull my race pads off between events lol

Ehh who cares, I've had 08s in my E36 for like 7 years. People just think you're a bus LOL.

With modern race pads there's no need to swap pads. They work without any mayor issues regarding cold function or disc wear.
20 years ago when using old compound as PFC97 then there was issues with disc wear when cold. Since PFC08, PFC11 or Ferodo 3-12 I haven't had any problems with cold bite or disc wear.

See the above comment by Obioban. When the pad isn’t in its temperature range, the friction surface behaves like sandpaper instead of a smooth, lubricated friction pair i.e. the squeal. This accelerates rotor wear.

This is 100% wrong. If you closely observe the brake dust it will be glittery which indicates your rotors are being worn down quickly.

High temp pads work differently than street pads. The tech has gotten better but there is still no reliable dual use pad that is quiet, has cold bite, maintains stopping power at higher temps, and has a long service life.

bigjae46 Do you think a drive-to-the-track type of car needs 2 sets of pads, one street, one track or is it acceptable to use only track pads (PFC 331/332) given the limited amount of street driving?
Say I typically drive 200 mi to a track and back, and never drive on the streets otherwise. One factor is that the 200mi is mostly highway.


Also, does anyone know whether or not there's a part number for 331 pads for the ZCP rotors? I just found 394.331.20.44

A limited amount of street driving isn't a big deal.

I'd be more worried about daily driving those pads which will chew through your rotors quickly not to mention using pads that cost 3x as much as a regular pad.

I drive to and from the track on track pads, to remove any transfer layer or deposits from the rotors (taking advantage of the hyper abrasive nature of cold track pads). Street pads go back on when I get back home, before whatever the next drive is.
