I know some of you have a lot of technical knowledge, so I figured I'd ask you guys  |
I have done some research, and asked a shop called trackspec who are making functional vents for z4m and he said that just by the hardware they have used, it has 400x more drag than appropriate hardware. And if they didnt consider that in design, makes him question how much design did they put into the diffuser itself.
So he is considering doing diffuser as well for z4m that is functional.
btw he tests his products at the track with a bunch of lines and some computer data....hes well known in california.
If people get more interested in functional diffuser, I could have him take it more seriously and start asap.
