Spoiler Speed
 

can any one tell me at what speed does the 90 gt spoiler become active or at what speed does its areo dinamic start to work

i think most spoilers on cars are just for show really. If you lok at actual track cars that run a spoiler, theyre huge, like the 00 cobra R. It needs to be up higher to play any roll. Then again Nascar spoilers are low, but designed differently. I really doubt it does anything.

I was watching some small chunks of loose snow ontop and under the one on my '02... they'd bounce around a bit... but pretty much didn't move even at ummm errr "highway speed".

Conclusion... show only.
