Just a quick comment on frozen rotors….
I have done extensive testing of cryo treated discs and brake components. This testing involved controlled brake dynamometer testing in our facility.

Long story short-
-If you exceed 800 degreed F (even once) then all cryo treatment effects are negated. (As if there was no treatment at all) So if you race or drive hard….forget it!
-Cryo seems to have the largest benefit for fleet applications where brake temps are low.
-Cryo of friction material is a waste of time.

Thank you Tim! That is exactly the sort of precise and diligent
testing that separates the science from the hype-artists.
Everyone who has ever considered frozen rotors should look
into Tim's services to see if they are an appropriate way to
invest some of the money he just saved you.

A testimonial... I just sent Tim an email asking a question about possible brake upgrades (oh gawd... please don't ask me why), and he responded promptly with some great information. I hope he & I can do some biz.

good thread!! Thanks, Steve, Joe and now Tim. I also have brake upgrade questions now I know where to go also!

I think cooling should be the focus. The stock brakes are powerful enough
to trigger ABS at 100mph speeds. The only problem is heat build-up,
heat-stressing rotors and boiling fluid. If you can find a way to duct more
cold air, starting with the GT3 deflectors, and maybe going beyond with
some custom ducting, you will probably get your best solution for the
track. Even if yo do spend thousands on different brake components,
they will all last longer and work better if you get all the cold air to them
that you can.

Agree Joe, since going with the pagids, castrol SRF, and the GT3 cup ducts have not had any brake problems even over two day events. Thanks for the good info.
