I was wondering if anyone knew where we could buy the parts needed to finish the brake ducts on our cars.

Thanks

There is partial ducting in place on our cars?

here's the OE ducting, i.e., not much of a duct really:



and here's what you can do to, perhaps, increase air flow:

Anyone actually use some 3" hose and duct air to the spindle?

[Nivek]

I think we need a sticky on this topic since it appears every week.

Does subaru offer the plastic pieces needed to finish this? The bottom plastic piece is needed to make it a tunnel, then a hose is needed to go from the hole to the rotor.

I found a brake duct kit offered by Zero Sports for the JDM. Joseph at Tarmac-USA ordered in a set (L & R). Here is a picture of an STi with the kits installed in place of the fog light covers (along with a different front body kit of thiers).

It only brings the air to the inside of the wheel well, getting it from there to the spindle/rotor may prove a challenge while maintaining adequate wheel clearance. We'll see. I do have the JDM front bumper reinforcement to put in at the same time.

I'll post pics of the installation and result. Here are the instructions that came with the kits - how's your Japanese?

That lloks to be exactly what I was looking for, Thanks.

those won't fit cleanly as the holes won't line up. With a drill you can make them work, but for that much effort save your money and go by some sheet metal and tin snips and make your own.

What if I remove the mud flap. How does that negatively affect the car?

Edited: to clarify the mud flap.

part numbers 59123 and 59123A - you'll also need a handful of 45687's. Total cost of around $20 shipped.
They were stock on the 2002 WRX Sedans but not on any other impreza i've ever seen.

Good tip, I'm ordering these now. Looks like we may have to drill a hole or two f or the clips to go through.

Removing that little guard did help cool my brakes a bit at the track the other day. I didn't have the plastic pieces needed to do the ducts so I took those off to get more air flow into the wheel well. Seemed to give me a better feel on the pedal for a much longer time. I had brake fade, though it's my own fault, my brake fluid is a year old and didn't want to change it until I got my SS lines.

Ok, I went for those WRX brake duct covers (parts link posted above). They don't fit the STi as is, but they're super thin and easy to trim with scissors. I just drilled my own holes and used some of those plastic clips to hold it in. They were pretty cheap so it's not a bad solution, but if you have access to some thin plastic you might as well make your own. Also as posted above I opened up that air exit hole to the maximum. Not sure how much it will help, but it can't hurt!

[TRM]

can you snap some pics of the installed pieces on the STi?
