Car Wind Tunnel Data

[BigMike]

The cd factor is not so important, but rather the air drag index factor, which is the drag coefficient x Frontal Area of the car (cd x A). The lower the number the more aerodynamic the car is.

Also many nose-heavy cars use lift in the front to become more balanced at high speeds.

Bryan-

If you find the pic of the MK1 MR2, please post it up!

[BryanH]

This isn't the one I was thinking of, but it might even be better.

Also check out the MR2OC thread linked in the above page.

And while I was looking around I saw some very interesting things. :)

These are all great. I've already seen the "bored of your old aw11" one, that is just ridiculous hahah

Soo clean!  Check out the screaming chicken on the rear roof visor

That is REALLY awesome, reminds me of this one from Japan, I really like the dark matte gray...





Also, I really like two tones on the MK1. Other examples include:

Allllrighty then, I like the ABS intake, let's do something similar.

Adding the MK1 MR2 airflow to this thread. Thanks Bryan
