That's 2.5" hose, right? That's what I plan to use... any issues routing it? I ask because I can't figure out why Stillen chose 2" hose in their kit... other than cost.

very nice job. The only way to really test it is to block off one of the hoses and take temps of both sides after a track session.

I accidentally ordered a 3" hose and I am having a little bit of trouble routing it, but I'm challenging myself to make it work. It's frustrating but I'm trying to take my time, the car is still on the jack. Worst case for the areas which don't fit, I'll have to make more custom parts.... =/ Which will add extra weight and parts....not to mention money and time.

Thansk for the great tip. I will definitely try that! How come I didn't think of it.

My mind was thinking of going the long stupid way of unbolting the whole thing to take temperature differences.

Funny I can come up with complicated stuff but can't think of an easy solution. I'll see what I can provide you guys after track. It'll be interesting as I'm going to Laguna Seca, I heard it's hard on the brakes.

More pictures...

I was basing my 2.5" assumption off your drawings... I suppose that explains the "accidentally".

Yea, I did some research online for track cars brake ducts to see what kind of brake duct flanges were available and I stumbled upon 3" brake duct flanges so I designed the front adapters to work with a 3" diameter hose.

It wasn 't until I started routing it and looked at other people who have done this kit uses a 2.5" or smaller. I already spent the money, I might as well try to make it work.

Try to think back, I was also trying to maximize the coverage of the front duct, I didn't like how the Stillen kit shows the 2 circles from the front bumper.

scruffy- i like the fact that you used rivots on the hose coupler on the brake rotor cover side. :tup:

it's a slick system.

Thanks! I actually did it on the other side first and I had to redo it because it stuck out too much.

No one worried about water build up in the hose?

any water is only going to splash on the rotors, like going through a puddle. Not like its going into the engine.

Water buildup=stagnant water when you hit the stop button :)

I dont drive mine on the street and don't track in the rain anymore, so its a non issue for me, but I still don't think its a problem. Unless you are parking it long enough to breed mosquitos.

I garage mine usually, take it out once a week or so yeah

Doesn't happen. I had ducts on my daily-driven S for 7 years.
