Hi all..

At what speed do aerodynamic car shapes actually start to have any noticable effect? is it right from the off... or from say 60 mph upwards?

I'm guessing its not something you can easily 'back to back' test.. as there aint many cars with identical power/character engines.
but 2 different body shapes

just wondering in relation to something else. thats all!

Thanks!

 

good question mate id probably say after 60 mph
when doing the 060-100-150 rainbird recons by taking that rear wrc wing off the back could improve the 0-100-150 and quater mile times by a bit
but thinks up to seconds on the 0-150 !!

 

its easily answered here by looking at say porsche/merc etc that lower or raise a spoiler at over 60mph under this speed i cant see any issues?

 

from the second you move air is causing friction on the body of car, the faster you go the bigger the effect.
