i totally want a set of those brake ducts.
can you copy yours or something?

 

Yea sure. Do you happen to have the new SPL tension rods? they are already tapped and have bolts for them. If not we can make clamps or something.

 

Thanks. Red paint wasnt my Idea, I just had it laying around and didnt want to buy new paint. Plus its a factory color, and the car was orignially burgandy so I figured it was close enough. And I had searched for the Navan stuff since I got the car over 2 years ago. I just need to find a bumper, just dont want to spend 500$

Actual brake ducts with hoses and stuff cost over 50-100. I did mine for free, and these work better on the street. I dont really need acutal ducts any time soon.

The diffusers are to reduce drag, because the wheels are actually the largest cause of aerodynamic drag. So those little things help push the air around the edge and past the wheel. And since the air is flowing better past the wheel and not directly into it (the tire surface), it reduces drag. Also the air speeding past the outside of the wheel creates a venturi effect inside the wheel itself and it actually will pull the hot/stagnant air out from inside the wheel/brakes/ and helps cool the brakes and the tires, because once you get on a staight and can get up some speed the faster the air moves past the wheel the more it sucks air out of that area.

I could of made them slightly larger to cover more area but I'm lazy and I think these will work well enough for me right now. And I still have to make some for the rear wheels as well.

 

You can see them in this picture. The ALMS race team is the one that came up with the idea.


And the C6R which run them as well, just more agressive. You can see how the actual bumper is the diffuser.

 

yes, i do.
theyre red and kinda shiny.

 

Sweet, I'll copy my set tomarrow morning. I still gotta put the A/C belt on the car.

 

are we messing with your car tomorrow?
i couldnt remember.

text me in the morning or something.

 

awesome!! thanks for the info bro... looks like something i might be interested in messing with after i get some seat time...

as for the ducting, i was thinking of some afro-engineered shit, like the alum dryer vent tubing maybe slightly flattened, with those "velocity stacks" of whatever those honda kids have sticking up, out, or beside their bumpers or windshields, painted flat back, and mounted directly behind the opening, or to the outside of where the OEM Zenki fogs go... kind of a rough idea, but a "ram air" if you will, and now reading about the wheel difusers, seems like something highly efficent... with the exception of the bright alum tubing in there... maybe paint it or something...

 

Aluminum tubing stuff wont flex enough when you turn the wheel and will just be a headache, and the plastic dryer stuff will melt. The neoprene hose you need is 50$ for 10ft of it and you can get any number of scoops to fit them too for any X amount of dollars. Unless its a full on track car you wont ever need that though. But I like free so I made those instead. They probably dont work as well as a full ducting set up but they still make a big difference, who needs all that hose stuff on a street car anyway?

 

good point!
