Why hasn't anyone come up w/ a duct setup for the WRX?
I've looked at putting something together for ducting to the front brakes and can't find what I'm looking for. I want a set it and forget it setup utilizing the oe brake vents. I've looked in Pegasus, Essex parts and many other racer wholesalers to no avail. I can find good reinforced silicone hose, but no ducts that would work for the oe vents. I don't want to give up my fogs and don't want to swap them in and out (realizing that the fogs would allow for more air). If anyone could point me in the right direction or if someone knows where to get custom ducts made it would be appreciated.
Thanks

Yeah, I saw those. Unfortunately they don't utilize our oe ducts at all- there supposed to be mounted underneath (I don't want to go any lowering in front). I think there was also a question if the hose was even high temp silicone. I'll keep bugging DBA Steve.

If you dont want to give up your fogs (why?!) then you are going to have a very hard time finding a good ducting solution.
The oe ducts are very small. I prototyped some ducting using dryer hose there, and it did not work well at all. It is hard to get the ducting around the full tire turning radius and into the wheel. i managed to get it in there, but being under the bumper, it was destroyed on curbing.
Some 2" hose may work better in this situation
but the best overall solution would be to put ducts in the place of foglights, run the ducting out around the manifold, and drop it straight onto the rotor. This is what I am doing now using silicone hose and a cut to fit duct that fits perfectly into the foglight hole.
hope that made sense

how many track days are you going to do? Is it that much trouble in your preparation for the track to remove the foglights and install some ducting in place? Once you get it figured out it shouldn't be too tough to put in and take out. You could probably even sell a kit to do it. Just do it before or while you're bleeding the brakes. Also there's a good chance the fogs will be destroyed by stones as well unless you remove them or have some kind of protection for them.
To be honest I wouldn't want to run brake ducts on the street anyway. No need.

The fog light holes definitely are the better option, more flow and there are NACA ducts that will fit and probably not too big a hassle to swap out for track days. I was hoping for a solution that I could set it up and forget it. I wouldn't need ducts on the "street", but I do some rather spirited mountain/canyon and gravel driving that would benefit from some additional air on the rotors. I do have mesh fog lamp covers (they actually work- I noticed a good ding in one the other day- I just pushed it out).
I may be pipe dreaming using the oe ducts. I do like the idea of selling a kit, maybe I could pay for a few of my mods

I can't comment directly on the WRX, but with one very minor inner fenderwell (plastic) cut, I ran 3" ducting on an 01 RS all last year to the fog lamp hole. I run a lot of track days and also run on the street with this car. I was able to attach the end of the ducting at the fog entry point with tie wraps and leave the foglight connector hanging. At the end of the track day, one connection and 3 screws a side and the fogs are back in place. Getting the air from the duct to the center of the rotor is the harder thing that I makeshifted some splitters to get a 1.5" hose between the caliper and hub...pointing right at the rotor center....and a 2nd one on the other side of the hub, pointing again at the center of the rotor. It's on my to-do list to make a better delivery system at the hub, but the rest of the system is invisible and worked all last season. I'm running WRX rotors and 4 pots.

Do you have any pictures of your ducting/venting install? I need to do something before the snow thaws-the brakes just get cooked at track events, and I get some bad fading.
Also, what pads do you use? I have tried Porterfield, and Carbotech for the last 2 sets ( 1 set was the Panther +, one was their higher temp set-don't remember the model name). I liked the Carbotech, and althought they cause tons of dust they do the job, which is most important! I am thinking about trying Hawk for the next set. I hear great things about Pagid, and my freind in the Porsche club all use them, but I have been unable to find them in the U.S.
Thanks

If you want Pagid, www.rallyperformance.com sells them.
And I would be interested in seeing the duct setup too ... I have two big holes on my bumper right now after selling my fogs

go to www.scoobymods.com, go under the brake section for wrx.the oe brake ducts under the fog lights are used with a plastic ram air kit that is available through subaru.itll cost u about 20bucks

Thanks. Already have those, came oe w/ the 02's for some reason. While they provide a small improvemnt, what is needed for track is a true duct system providing air directly to the rotor, preferable as close to the center as possible.
I've come to the conclusion that the fog light location will be easiest, they make a couple of ducts that should fit very close to perfect. Then some 2" brake ducting routed to the rotor. The difficult part will be to fab something on the dust shield to clamp the ducting to. I may just locate a couple of dust shields to play w/.

Just ordered ducts and 2" brake ducting, so will be tackling this very soon. I will be going through the fog lights- very easy to in/unstall (three screws and a plug). Will post results when complete.

after reading the post on scoobymods, i had to run out to the car to check my wheel wells for the opening. I have never noticed it before now. i'm amazed that those OE vents actually serve a purpose other than looks.
