Haveing read that the M5 came with alloys designed to cool the brakes, what ones cool the Mini brakes the best?

Or what design would work best?

10", 12", 13".

13 inch 4 spoke will have the biggest gaps in the wheels

but do mini's have a problem with over heating brakes ?

[smudger]

Depends on how hard you work em!

But I was just wondering which ones have been made just to aid the cooling, and what design would aid cooling.

I know the revo 4 spoke design is one of the best for cooling (& lightness) but the spokes themselves arent angled to direct the air onto the caliper/disc.

Oh, and whilst thinking of the air flow, would this make it a problem with water/road grit onto the pad?

i know the mercs slr have wheels to direct airflow, but i guess thats useless info....
the clk gtr have ducting that flow air into the rear brakes from the inside out. im guessing you could mock something up that would turn with the wheels

most effective wheel design has go to be like this else it wont go far.

Well i can't really see the point in cooling brakes on road cars, but if needs must, then just pick up a motorsport catalogue and scroll through untill you find the brake ducting section where they have them that replace the disk backplate with a moulded carbon air duct.

Cheaper and more effective.

Very early Minis had a full width front apron. The ends were cut away from later cars front panels to cool the brakes. Enough air comes through these cutaways, unless you fit a dodgy bodykit.

Would mambas not be the best? seeign as they are 4 spokes but have holes in each spoke?

i mean like this lol

Well we all know that trying to fabricate 'fins' to fit to the wheels is out of the question, as drag would be an issue on a low powered car.

I think one of the reasons that Cooper Car Co developed the rose petal style alloy wheels was to increase the brake cooling of the touring cars of the time. This then followed when minilite started producing alloys.
The vented s rims did not aid brake cooling as much as the rose petals.

Anyone else heard of this?

To be honest, at the speeds most minis go, I don't think anything to do with the wheels will help cool the brakes.

yes, i had heard this about the rose petals, but cant remember where

But the ERA Turbo had cooling vents directed to the brakes to cool them down, and given that it was a well thought out car, then they must of thought their was a need to cool the brakes down.

Also, i am sure i am not the only one who has boiled his brake fluid due to high temp caused by brakeing (what can i say, lol) so their is an issue.

Whilst my car is an open wheeler and dosnt need venting to the brakes, i was just wondering if it has been done.

The easiest way to improve airflow to the disks is to remove the shields from behind the disks. The Mini Copper Register recently ran a trip to Monte Carlo and the route took them over the alps. Quite a few cars experienced brake fade coming down the mountains and the problem has been discussed in the last few issues of their monthly magazine and removing the shields is one of the suggestions that came up.

[smudger]

Do that anyway as standard, however, i was thinking about a wheel design that directs the air into the disc.

Just curious.
