I am following this post since i decided to upgrade my brakes to BMW Performance on my 130i hatch.
I haven't done any trackday events since i installed the Performance brakes.
I am using a 5.1 dot racing fluid (not Motul). I have of course the standard brake pads installed.
Maybe next Sunday i will do a "light" track event... and will film from inside the cockpit.
I am curious to see if they last 2 laps as some people say. I have my doubts.
I normally let the brakes cool down after 10/15 mins or so... that is mandatory i guess.
I always do this during trackdays.. unless i am chasing someone really hard so i try to "last" for one more lap to pass him and then cooldown.
Unless you have a "real" Brembo BBK this is the only way to prevent OEM brakes pads and OEM rotors from getting melted/warped and save top $$$$ (Euros in my case).
I guess if i do the full 20/25 mins of spirited driving/braking yes, the OEM pads would have melt and the OEM brake rotors would have warped.
This vid is from November.. with KW Clubsport, Quaife LSD and H&R sway bars kit installed but still with OEM calipers + EBC yellow pads + 5.1 dot brake fluids.
(Save it to hard disk first...)
Did not have any fading problems at all (it was a full day at track).
How do you track your 135i ...?? Do you let it cool down after... 10 mins.. 15 mins.. 20 mins... or ?? Please share.
PS - Any news about Brembo pads for the 135i/Performance calipers?
