Building Bargain Brake Ducts From Porsche GT3 Parts?

Here’s a cool tip that we learned from an online MR2 community: late-model Porsche GT3 front brake ducts don't cost much and can be adapted to a wide variety of cars.

How cheap? Well, we got a set from FCP Euro for less than $12, plus shipping. You’ll need one for the right and one for the left.

Just as we saw on the internet (isn’t it nice when the internet is right for a change?) they clipped right onto the trailing arms of our 1991 Toyota MR2 Turbo.

Various browsing has revealed that owners of Toyota 86 twins, Honda Civics, Preludes, Nissan 240SXs and others have successfully used these GT3 deflectors as an easy, snap-on brake cooling augmentation.

Any car with angled front trailing links less than about 20mm in diameter should be able to easily receive these deflectors. And if it doesn't work out, well, you’re only out $12 for some genuine Porsche GT3 hardware.

How to adapt these parts: Make a few cuts and throw some zip ties on there. It’s still cheaper than even a trip to Lowe’s for dryer vent.

Now that is really cool!!!!  like you said I would maybe consider augmenting the attachment with some zip-ties but that is a great tip!!!  Wonder if I can make them work on a 951.

Just ordered up a set for my AE86. For $12 hard to go wrong. (Plus I can say I have fancy Porsche parts on my car)

After a little more research I found that these are an upgrade for my 987.1 Cayman and can be modified for the Cayman rear brakes. $34 shipped.

You are all such enablers...

I remember having to buy a non-gt3 one for my boxster to replace a mangled one and it was more expensive than a pair of gt3 ducts.

Sort of related, but when I had to replace a tie rod end on my 911, the Turbo piece cost a tick less–and that's the one that offers tighter handling. So that's when I did the upgrade.

Yes! I have a pair of these on my MkV GTI from when I was tracking it, pre-mustang. They clip right onto the control arms for a FSI engined car. Not the TSI, though, since the control arms have a wider cross-section. They hung down a fair bit into the airstream and made a noticeable difference in brake fade at Roebling Road.

I do not have a use for these yet as I am back into autoX, but I will order a set just to have JIC for that price

And in true Pcar fashion, these will go NLA and become worth 3,245 bucks a piece 4 years from now. Buy a hundred and pay for your kid's college (or tech school).

In reply to Olemiss540 :

LOL I was thinking the same thing adding them to the cart.  I mean, 5 sets just to get to the free shipping...

*sigh*

The Cayman has one tie rod end that needs to be replaced soon...might as well get both if the turbo ones fit the 987.

Another option is the Audi RS3 front brake deflectors. They are a little large vertically and have OEM zip ties to secure them to the control arms. They work well on just about anything with a front control arm.
