A picture of my extra brake cooling set-up in action... The holes are next to the original brake cooling ducts. The OEM set-up is more tire cooling, then brake cooling. The extra cooling is directly aimed at the discs...

Slightly off topic any more pictures of your car?
It looks ace........... wouldn't have ever considered gold wheels with a silver car but it seems to work.
Your brake cooling is now a scheduled winter mod. :thumbsup:

My CSL wheels are not gold... (Maybe it looks cool?) They are dirty in this picture... This is how the car looks clean ;)

Looks good, very discrete. Did you find significant benefits even with your AP set up?

Because the OEM Z4M brake ducts are not the greatest in cooling the brakes I looked for something extra. I never had fading with the AP & Pagid set-up. But on some tracks the Pagid brake pads and AP disc were getting really hot. Sometimes I had a vibration steering wheels after some intensive hot laps (the brake pads get a little to hot and some pad material got stuck on the AP discs) . The extra cooling helps to address this problem...

The OEM brake cooling ducts are just decorative as far as I can see! I've had exactly that from EBC Bluestuff pads on OEM discs. I'm going to try the brake cooling ducts before I spend a couple of thousand on brakes (although I am prepared to spend the money if I can't achieve the results I'm after).
Do you switch off the DSC on the track? I always turn it off, but on the rare occasion I've forgotten, the brakes have become extremely hot very quickly.

Use a hand-held Infra-Red thermometer to check your brake disc/pad temps after being on track, with both OEM and cooling ducts to check if there's any difference. The hottest I've see immediately on stopping with cooling ducts is around 320 degsC.

Hi John! I have one so I shall :thumbsup: I think the easiest way will be to fit the cooling ducts then to make test runs with and without bath plugs in the sink waste pipes :lol:
Of course, it'll be February before I'm back, so there will be added environmental cooling taking place too...

Clearly carefully considered, like all of your engineering projects :thumbsup:
