[dspillrat]

Man,
You gotta get more air to your brakes.... At least 2 ducts, 3 needed to keep things cooler at Road Atlanta......hat on caliper, and 2 to the rotor...... Its not pleasant at pit out on the 10th lap hitting the floor...... Can ya say dirt tracking brakes!!!!!

I gotta get on the track!!!! Any Track!!!

Dave, Here is a link to an old thread that has pictures of ductwork.

I don't have Katmans's pictures on this machine so I will post them up tomorrow along with Parrish's set up.

Mike, shoot me a pm with your email. I want to talk with you about the ducts you have built. I need an alternative to the caliper hat that I currently have.

Ok, here are the pictures of other racers solutions to Z brake ducting.

i really appreciate the help guys. Where does the second inlet come in from the front of the car. I have 1 on each side of the airdam. Do you cut 2 more holes in the airdam?

Dave,

I have a single duct in the face of the air dam per the GCR. It splits into the 2 lines that are then routed to the brakes.
Here is a link to my set up as I found it from the PO.

I have replaced the dryer duct and changed a few other minor things but you will get the general idea. My set up makes it interesting when changing rotors. I hope to alter that later this year.

You can use other exising holes to from which to duct the brakes. The air dam has a great big hole in the center.

Thanks Paul. I was wondering about adding holes because of the rules. Do the 3 lines that Katman used all come from a single inlet?
I see I've got some work to do this weekend

Chet's old z, the one that won the ARRC, had 2 ducts on each side of the air dam and 2 ducts attached under the bumper that went through the large center hole in the airdam. Totaling 6 ducts. I have a picture somewhere. The GCR denotes the ducts allowed in the airdam by total size. And the center section isn't really the airdam, its an existing hole. So they (Katman and Chet), had a duct for each of the 3 hoses that ran to the brakes. I don't remember if they ever got protested, or what happened if they did. The airdam ducts didn't go over the total allowed area for the airdam. As I recall. (I could be remembering wrong, and I'll try to find the pics)
