Pictures of my custom brake duct inlets
5 Attachment(s)
After trying a few less than satisfactory methods of plumbing my ducted front brakes to the front of the car I went ahead and had a friend of mine that works art a BMW racing shop fabricate some custom front brake ducts. Attached to this post are some pictures.
They're made of aluminum and are fairly low profile so they won't scrape easily on dips or driveways. I think my friend went a little over kill on the inlet area. But he insists that you should have an inlet area that is 2.5 to 3 times the side of your duct hose. Yes, I'm going to paint the little red bolts that hold the bottom of the duct to the lip spoiler black at a future date. I have not yet tried these at the track. My last setup worked well at the track but hung down too long and would get ripped off on the street on. I expect to run at Buttonwillow raceway next Sunday so I'll see how they do. |
Looks weird from the front of the car, but its obviously not there for looks. Totally BADASS man!!

Ya...I laughed at the 1st and 3rd pic but the rest are very impressive. I don't think I would have this setup for a street driven car but otherwise very nice.
|
Paint them flat black like the lip and you won't hardly notice them. Maybe even trim them back a little bit to hide them some more but they look good and functional.
What kind of duct do you have on the brake side? The Ntech ones? |
Awesome work, very creative...
|
how visable are they when the car is sitting on the ground?
|
Mazda was out of R1/2 brake ducts? :p:
|
Very innovative man, do have any pics of the car on the ground? That way we can see how visible it really is.
|
Nice work, definitely paint them!!
|
You should paint the duct black also. If I saw your car in a parking lot, and I looked for stock brake ducts, and I saw these actual enclosed ducts in its place, I'd be like :eek:
Nice job. Jeremy |
Actually it's not super noticable when the car is on the ground. I'll post some pics later. The fact that the car is silver helps make them not stand out too much. But you all are definately correct that if I paint them black they'd probably blend in much better.
Yes, the brake rotor backing plastes are from NTech.

That's when I decided to let my friend help me with the setup I have now. Of course this setup is entirely unneccessary for street driving. But I hope it will provide two things: 1) Large enough inlet area to work well at the track 2) Low profile enough to not scrape too often on the street. |
i agree! flat black would look great

Those look very slick. A little paint and they'll practically disappear.

Nice job, you're ducts look sweet! The best part, is that they look extremely functional. You'll have to let us know how they work out on the track!

Update... so I've had these on for 8 months now and about 10 trackday weekends. No fading at the track even when I beat them as hard as I can. Work great on the street too! In other words they haven't ripped off when I've taken a dip or driveway too fast. Still have not painted them... I'll get to it.

John, out of curiosity, do you know if the hose is necessary to direct the air? Do cars like the Porsche Turbo have hoses after the duct in the front bumper directing the air as such? Or is it just done w/ an inlet + fins, and air moving through the fender lining, as I understand happens on the R model FD's?

are there a circular areas on the back ends of the r1/r2 ducts to clamp the hoses onto? or does someone here have any pics of the back side of the ducts out of the car? |
Having a dedicated hose directing air directly into a sealed center section is the best for cooling. It will ensure that all the air from the duct inlets is pushed through the vents in the rotors.
I'm not sure how many factory cars if any have a ducting system exactly like the setup my car and other track cars have. Most factory Porsches I've seen have brakes ducts that just direct air at the brakes. Kinda like the R1 but a bit better. |

Just curious, are you running stock brakes?

those are nice but a brake duct from www.racerpartswholesale.com/ should be good enough. They will just take a little effort to fit. This is what I plan on using with the ntechs and a ap kit. I just have way too many projects. They are plastic but only $15 a peice.
Or have you tried something simular and it was not good enough? Mike |
Looks awesome man. Sleek and functional, can't ask for a better pair. Great job john.
