Porsche gt3 or Audi rs3 brake cooling ducts?

[86salmon]

Trying out using brake cooling ducts for Audi rs3 or Porsche gt3. I the idea of trying the Audi from a user on 11gen forum. I figured why not. They were $35 on eBay

There's an article on Grassroots Motorsports about the gt3 ducts, from bmw to mr2, with impressive results. I figured that a pair for $24 shipped from FCP Euro, why not??

Gt3 top
Rs3 bottom


Test fit the rs3 first

After inverting, reversing, and some trimming I got to this point. Unfortunately, they aren't aiming at the hubs

Onto the Porsche

Aimed at the hubs and strapped in

I'm concerned about dragging, but they're plastic and at the price, a throwaway

Hopefully they'll be of benefit in the brake cooling department

Thanks for sharing! I've been looking at getting something like this for my Miata after also reading favorable brake test results. Honed Development makes a kit that clamps the air guide to the front sway bar. Once I finally purchase a kit I'll test it out on the Civic first to see how well it works.

That kit is a little pricey. I've found the gt3 ducts for $5 plus shipping at FCP Euro and a couple other sites. I'm looking forward to your results though. More options are always good

Yeah I agree you are mostly paying for their hardware more than anything. Still cheaper than a set of brake cooling ducts and nearly the same results according to the testing from Honed albeit on a completely different car.

Isn't it possible to retrofit the fl5 or fk8 brake duct and deflector?I think the Honed dc5 air ducts might have the best fitment on the 10thgen. Seems easy enough to make a duct from the foglight true the inner fender liner.

I think it could be possible. Aren't there hpd ducts in the place of fog lights?

Again, it's hard to beat the price of gt3 ducts compared to the other solutions

Yeah as cheap as those gt3 ducts is not going to be beat .The hpd ducts are around $400 .Would be great to see how those are routed .
I had a look at the FL5 parts and those are not that expensive .If you used the round connectors (16 ,17) and the air ducts( 12 ,13) then you could make a connection with some plastic tubes from the fog light up to the round connectors.The FL5 air ducts has 2 mounting point with m6 bolts .So it's easy to bend /make a bracket.

That is rather interesting from an aero point of view. The current setup I have with the gt3 ducting is adding drag

Well this also adds drag but I guess the air exits out of the fender area again. That Exits higher then the lower air scoop which would disturb the lower air pressure.(downforce)
