Hi guys,

I just wanted to show you what I've been up to lately. I've made an carbon air scoop to provide the brakes with more air so they will be cooled better. Mainly the RS3 has this problem, but also the TTRS doesn't have the most perfect OEM brakes (understatement).

In the pictures below you can see what I made for my TTRS. Basically it will fit any model car but I designed it for the measurements of the TT.
The product is 1mm thick and 15mm in height so that there will be no issues with lowered cars and speed bumps. The shape is from wide to small which creates a vortex effect forcing even more air going to the brakes.

I know a couple of people with a RS3 8V and 8P that have issues with their brakes becoming too hot which will result in vibrating brakes, this would in my opinion certainly help in more cooling.

Recently also a test was done with and without cooling.
The right front wheel had a carbon air scoop and the left front wheel didn't.
Two times a emergency brake test was done from 150 km/h to 10 km/h then the car was brought up to 130km/h and for 4 times the car was slowed down to 80km/h in a short period of time.
After this the car was driven for a short while to allow for cooling after which the brake temperature was measured.

Conclusion: improvement of 23,6%.

Soon I will repeat this experiment with GiroDisc breaks on my car as I will receive them in a couple of days.

P.S Abovementioned taken into account that the right front rotor will always be hotter as the left one as Audi only produced one kind of rotor (for left and right) so actually the right rotor is going in the wrong direction.

In the picture itself the values are in Fahrenheit.

If anyone is interested in these, please sent me a PM.

Really?
Surely a bit of plastic would have done?
 
Indeed plastic would have done, but carbon is more brittle. Although the scoop is only 15mm IF you would hit something this carbon scoop will shatter and not rip your skid guard out underneath your car. That is why it is made of carbon and not from sheet metal or anything else.
 
Ah ok, can see the logic in that....
 
Read about that on vwvortex.com .
I'm interested to see what the resulsts will be when you fit the GiroDiscs!

Although we 8V owners need to cut away some plastic underneath to make those vents work isn't it?
 
That's is an option or you could place them differently to get the same effect.

Or you cut a bit of plastic as seen in the images.

Thats what it lookes like underneath the RS3. I think the vents won't be as effective as they're at the TT-RS. I don't know whether there is a good place to put the vents. Maybe in combination with something like this? http://i39.tinypic.com/2a4pkyx.jpg
