I'm using the Mk VII front brakes, and have the back dust shields as well. Did most of you use it, or left the rotors open? Has anyone added any sort of scoop or extra vent to allow for more cooling? I'm thinking of adding some sort of extra scoop to get more air through the rotor.

What have you guys done here?

Heat is not an issue with the brake ducting so I used 3" plastic hose from a woodworking store that is used for vacuum systems. Bends well and works fine. And is MUCH cheaper.

Obviously this is not an FFR but you get the idea.

Great concept. May have to do this as a winter upgrade. Do you have any more pictures of the front-end where the scoop is mounted??? Thanks.

No more pics but I used a duct from some racer place and cut it to shape the configuration of the body. Held it in place with a bracket and silicone.

I have read that the ducts are not a good idea on a street car. They insure that any dust and rain that get picked, up actually get applied to the brake rotors.

On a race car the added cooling is more important than the added wear.

Don't know about you but I don't drive in the rain. I've had the ducts on for about 10k and have noticed no adverse issue with the brakes or rotors. Seems ok to me.

"Racer's Wholesale" sell the hi-temp flexible ducting and various scoops that can be made to fit. The setup sure looks neat but I don't know if you'll find there is any advantage to brake ducting for the street. The plastic vacuum hose would probably melt if used at the track, but the additional cooling sure make those expensive track pads last longer.

The plastic hoses, in my application, do not come into contact with any heat. I've had it on the track and they are in the same condition as the day I installed them.

Hey...wait a minute...I just thought of something. The rain? Hey, there is so much water being thrown on those rotors by the tires, puddles, etc that the duct is meaningless.

How about the dust shields behind the rotors? Did you guys keep them, or toss?
