One thing i've noticed while on track is that little air gets to the brakes on the MS3. They get very hot very quick. Then they fade away, far away and you end up at the end of the back straight going 125 with little bite in the brakes. That's fun .

Because of this i came to the conclusion that some ducting to them would help out. I haven't done anything yet, but have started to think about it more, picturing wonderful cool air flowing onto the brakes! Ah, what a beautiful picture! So tomorrow i'm going to take off the wheels and start poking around and formulating a plan of attack. Before i do, has anyone here already done something similar or could provide some idea or insight?

My dad had some brake ducting on his old 911. It was actually a shopvac hose and atachment. It sound getto but it actually looks just like the true brake ducting and was about 1/4 the price.

It also melts

Oddly, I have installed a fair amount of brake ducts and can help you with your project if you need it.

I am strongly considering installing the Boss 302 lower fascia and some brake ducting on my Mustang after the dismal brake performance I had at the track last Sunday. I am going to try using some Hawk HP+ pads first.

What melts? vacuum hose?

He actually had it all on the car before he bought it and it was still on the car when he sold it. Never melted and this was on a dedicated race car.

Hmmm, cutting that is something i definitely would rather not due, but if all else fails then this is a good option. Thanks for posting it!

I've read and seen some people using dryer ducting. I'll take a look at the shopvac stuff. Thanks!

Odd right? I would love some help! I took some photos and planned a bit when i rotated my tires. I'll post up the photos and my ideas when i get back to my computer. Would love to get some feedback on my ideas. Thanks!

Any progress, Andrew? This seems like a great idea. I don't know that you need plastic ducts like the dude from msf. Maybe just remove the brake dust shield and fit a small wing or air dam that directs air to the wheel area. Just removing the shield and having the inner side more open to airflow would probably help with cooling.

Does that thin shield serve any purpose besides trapping brake dust? Safety? Is there enough airflow beneath the car that you could funnel some toward the brake/wheel and make any difference? Or would it have to be pulling from the front where it's higher pressure/velocity air to be effective?

Keeping them cooler could certainly make the one brake setup for both street and track more feasible? Though I'm kind of leaning toward just changing out the front pads with XP10s for track days.

Good luck with it and let me know if I can help out. I've worked with composites and foam molds before and if we found a good spot with some airflow beneath the car, fabbing up a carbon or glass fiber "diverter" would be fairly straightforward. Maybe.

I haven't quite yet. I've been meaning to post up the photos and my ideas but just can't find the time outside of work. I have a day off tomorrow and will post up.

The dust/heat shield is to protect the rotor from what i've been told. I know a lot of people who run without it and have never had a problem. And i'm with you. I think there are ways to get air in there without cutting it or losing the fogs. Will post up tomorrow with more.

I would like to see how it works out!

Got busy today brewing and couldn't did the time. Sorry guys. I'll try to post tomorrow.
