Gaute's already been on me that I REALLY don't need any brake upgrade whatsoever
The pic is from Mantorp and to be honest I was very surprised with the temperatures I got. I've driven an M3 E36 3.2 for 10 years. It was over 250 kg heavier than the CSL but also slower... Its brakes got hot but not crazy like this.
I've ordered the TMS brake ducts that you fit on the spindle. Already have the air hoses which I bought from Tom Schirmer for some ridiculous price on impulse after he had a good laugh seeing my previous M3's sad looking blue and grooved brake disks on a visit to the Ring two or three years ago. Never got around mounting it on that car though, it really wasn't that necessary.
So no one here is running such a setup? I think it'll work well. I hope.
