and that Navan aero is so goddamn sexy, i need to get on scooping mine up soon...... love the sheet metal work to, although i would run ducting to brakes myself...
one question, what exactly are the front wheel diffusers good for?
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.
