Thank you for the very helpful information, the pit crew trials idea is great! and also to the other poster, thank you for the link.
So if weight is the main priority should I not worry about chasing a very low Cd? I have managed to achieve 0.38 but going lower is taking a lot of time designing and testing in the tunnel do you think its worth it?
Also, if anyone knows of any 4 wheel vehicles that have gone to Cd's of as low as 0.2 or even 0.1 could you please tell me the vehicle details.
Thanks
