    04+ brake duct setup

    This tutorial will be similar to the one I did for 02/03's-http://www.clubwrx.net/forums/showthread.php?t=62506

    What you'll need:

    a set of oe fog surrounds
    3' of brake duct- you don't need high temp ducting, regular will do- either 2 or 2.5"
    www.racerpartswholesale.com/duct.htm
    2 duct reducers either 3->2.5" or 3-> 2"
    www.racerwholesaleparts.com/naca.htm
    2 plastic "connectors" found at the hardware store- don't really know what their application is (they were threaded on the inside)- anything that will fit into the duct end and then into the wheel well
    four appropriate size hose clamps

    The reducers will fit into the oe fog surround, you'll have to do a little bit of filing/dremeling for them to fit, squeeze the reducer and it will go in it will be snug

    view from bottom- I drilled a small hole and used a plastic fastner (same as used on the rubber intercooler seal) to help keep it in

    You'll need to remove the fog lamps, I've elected to leave mine out (never used them as they were covered)- you could remove them for track days easy enough and then put them back in

    Use ~ 18" of your ducting and fastener the "connector" to it w/ a hose clamp



    I angled mine to help direct the air

    Use a hole saw on a drill (wheels need to be removed)- either 2 or 2.5" depending on the ducting you went w/- you may have to doa little filing w/ a round file depending on the "connector" you have chosen

    You can see from the pic where this is located when you look at your wheel well- this keeps well out of the tires way

    from the front push the "connector" end into the hole- should look something like this:

    Now all you have to do is connect the other end to your reducer

    Day to day driving I use the STi covers- leaving the ducting in place, track day just unsnap the cover and attach the ducting to your oe surround w/ reducer- two minutes and functional brake ducts

    Nice job. A similar setup can be made for the bugeye models using the mesh fog covers to prevent debris from going through, not that it would be a big deal.

    It'd still work if a guy wanted to run his fogs day to day, you'd just have to take them out for track days (they wouldn't get busted that way too)- would only take a couple of minutes to remove them

    i've been thinking of doing this to MY03 for quite sometime now, just haven't had the time to get around it - and was actually contemplating whether it is worth the trouble..?

    noticed any difference Big Sky?
