My brake ducting solution

[pseudorealityx]

Not satisfied with "just" the RS3 ducts, I got some 2" brake ducting, and some aluminum flanges and did this back in September.

I think this routing will only work for the GTI, because the R has more crap in the way. Maybe if you get creative. Also, I think 2.5" could pretty easily work, but I think 3" would be hard to get the routing without being too close to the accessory belt.

The ducting was from Pegasus racing, and the flanges were from here: https://www.aircraftspruce.com/catalog/appages/ductflanges.php

It's not perfect. I still need to trim away most of the the dust shields, so some of the air is certainly just hitting the back side of the shields. With a quick shot of black spray paint, wouldn't be too noticeable either.

Looking at these pictures again, I think there may infact be enough room to utilize these:

Would require some more trimming, and likely longer (read: new) ducts, but it would work a lot better than the current setup.

There are several thoughts on this, & I would opt for removing those hoses & placing into the splash shield...

Leave the RS3 ducts to direct air to the calliper/hub inner disc area...& then cut a hole in the splash shield, mount one of those air duct metal flanges to the back of the splash shield & then your hoses to the the flange...so two separate lots of air flow.....the hose mount like this:-

APR make some nice carbon fibre shields..

It what they do in racing have an enclosed ducted splash shield

I like it! think i've seen something similar before. Gotta ask, wouldnt it all make noise as the hoses get jostled around when the control arms are miving going over bumps and stuff?

Yeah, that's essentially what I think... getting the termination of the ducts closer to the splash shields.

My concern is that, as opposed to the S2000, our calipers on the front of the rotor, and there's an axle in the way that needs to articulate. I'm not confident I can get a routing layout that can get around to the "back side" of the rotor where there's a lot more room for an inlet on the dust shield.

And this is still primarily my daily driver, so there's a limit to the craziness I'm willing to do.

I haven't noticed any. The piping is quite flexible, so it just articulates along with the LCA.

Nice work. I'm about to do something similar on my mk6 but I'm going to delete the fog lights and make a shroud to fit in there

As we say "proper job"...

i'm honestly suprised i haven't seen more of this happening on the mk7s, especially those who had the fogs deleted from the factory in 17.

If there was some nice integrated solution for that, or if this car became a primarily track based car, I'd definitely do that. Post some pictures when you've started.

There's a company called versus that makes a kit but they want some insane price, think it was around 600 LOL NOPE
I'll likely be around $100 all said and done. I'll post pics when I do it

Just off the top of my head....

Route the hoses high exiting the engine bay to the back inner side of the damper/spring...aim for fastening the hose to the underside of the spring platform...then bend hose around the underside of the spring platform until to reach the flange in the splash shield which would be in the top half.....

the hose can be rigid with no movement required whilst it is cable tied etc to the damp under the spring platform....the only movement required is in/out & updown where it leaves the damper & goes into the engine bay..

The frame/serpentine belt are going to interfere on the right side I believe. Especially if I try to go-to a larger duct.

Just shift the engine over..easy job!...

(sorry couldn't resist on how to turn a simple job into a highly complex overhaul!)
