Thanks for that, I remember seeing that site years ago, but had lost the link.

I don't think pulling air in with the wheels is good for aerodynamics. It probably is a lot better to use intakes at the front of the vehicle with ducting to the brakes. Maybe you could even put high powered fans in there to provide cooling at lower speeds.

Well the least drag for sure is just a smooth cover. But since I need brake cooling as well as down force, or at least lack of lift, then having fan wheels does work by sucking out some of the air from under the car.

We produce these parts in carbon and can fit from 14"-18" rims

How do you attach those?

composite World · 09-16-2011, 08:07 AM

Its a two part component it has an inner cap which is fitted to original wheel nuts then the main part is attached to inner cap,the wheel nuts need to have threaded holes put in them for fixing,and voila!! instant brake cooling.
We have feedback from our customers that it reduces about 100°

Very cool, looks great, have a website?

Kinda related. These wheel covers are flat but perforated. They would allow some air flow but don't create flow, beyond whatever the wheel behind may do. From my post http://ecomodder.com/forum/showthrea...tml#post250009

Just off the top of my head (gotta let some of that hot air out) might reduce the vortices usually formed at the top rear of the front tires, and possibly the jetting vortices formed at the front of the contact patch.

Sorry to repeat myself. I posted that link on another thread. But here's another one which is pretty damned interesting in its own right. look at fig.9
