Carbon brake cooling modification

    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.

    Can you please provide more information?
    Is this air vented/routed after your scoop in the OEM under body panel? Or is it already routed stock on the TTRS/RS3?
    I have just installed a RS3 brake setup to my A3 8p and would like better cooling when at the track.
