Hey guys I'm practicing working with fiberglass and there are a few things I was to try making and one of them is brake ducts. I dont have a R1 so I've never seen them.

Can anyone tell me the route they take under the car or show me a pic of them??? I would be interested in a pic of the R1 and the CWC's. I went to the cwc website and they didnt have any info on them, not even pics but I know they made some.

Any info would be appreciated. The main thing I'd like to know is where they enter the fenderwell at so that they dont get hit by the tire and the tire doesnt block the air flow.

Or if anyone has thier own ideas about a brake duct I'd be interested in hearing about it as well.

Thanks,
STEPHEN

The R-1 Ducts are just small rectangular ducts tha go under the stock front end from the scoops on the R-1 spoiler to the front of the wheel wells - the CWR ducts replace the stock brake backing plates and have a large scoop mounted to them that faces forword.

The R-1 ducts do not extend into the wheel well but just mount to the bottom of the lower splash shields under the oil coolers. If you look at the bottom of the shields you will see some alignment ridges and slots for mounting the ducts (the duct itself is basically a flat "U" shaped piece of plastic).

So the CWC replaces that backing then. I was wondering how that would work cause it seemed like the backing would block the air flow.

Not to sound to much like a dumb *** but I'm not a big time brake buff......what is that back plate actually for???

It serves two purposes -
It acts a a HEAT sheild to protect the suspension from the heat generated by the brake disk, and it also has a small "scoop" formed into the front of it to direct air into the center of the disk to aid cooling.

What is the CWC duct made of??? I figured the duct portion was made of carbon fiber like a lot of his other duct/intake stuff. Does he make it into 2 pieces like a carbon fiber duct that just points to a alum backing plate or something like that?

The CWR duct is one piece all carbon fiber - it replaces the entire stock backing plate.

Spoautos: There is a good write-up about the CWC brake ducts here:

Any other questions I'd be more then welcome to offer up my experience with the CWR ducts.

It's a great site, your attention to detail is amazing. Very nice work.

Crispy - Hey man, those pics on your site help a lot. I do have a question or 2 for you. After seeing and owning the cwc ducts have you (or your friend) noticed a direct imporvement with them on at the track? Did they seem to make a good difference? I am still running stock brakes and just want to help them out as much as possible so I dont have to drop a ton of $ on brake upgrades....for now anyway. I really just want to know if there is a real noticeable difference...especially with stock brakes.

Also, if there is anything you could have changed with them what would it have been??? Say you were designing your own, would you do it just like the CWC or would you change a few things?

Thanks man,
STEPHEN

If you want to see a very functional brake cooling duct setup check out: http://www.kllr13b.com/index.cfm?fuseaction=brakes . The setup collects air from the front of the car and routes it via hoses to the backing plates that have 3" snorkels on them.

Crispy, i was waundering about the CWR oil cooler....how well does it work?

Here's what the R1 brake ducts look like:

Sorry guys for being out of commission for a while...that other thing called work.
SPO: Performance wise the ducts work very well. Specifically cooling the brakes. Almost too well on my car. How can you tell? Pad wear. On my car using the Hawk Blue pads on stock brakes without the ducts pad wear was very minimal. Pads were at the top end of their temperature range (as noted by temp indicating paint) Now with the big rotors and the CWR ducts temps are way down and pad wear is much greater (lower pads temps deos make them wear faster). Have the duct *improved* braking? No. Will the ducts increase the margin of safety before the limits of the stock brake setup is exceeded? Yes. Can the limits of the stock brakes be exceeded? Certainly but you have to be really hauling and be on a track unfriendly to brakes to do it. Will you see a benefit on the street? Sorry I can't answer that. I never push the brakes hard when on the street...no real reason to IMO. BTW I can fade the stock pads in one corner (T1 at Summit Point) when on the track...even with the CWR ducts.
FWIW a fully ducted brake setup like Sergio's is the real way to go but there often times are interference issues with the hosing used. Nothing is without compromise. IMO the CWR ducts are easy to install and work well. Well enough for pretty much anyone doing hotlaps.
Scrub: I have no personal expereince with the CWR oil coolers but I do hear they work VERY well
