How effective are OEM spoilers for our cars? Are they just for the look or have some function as well? I know that the Porsche cars have pretty functional rear spoilers. I've also heard that an F50 produces so much downforce that when driving over 200mph, it can drive upside down. I dont know how true that is though.

 

um no
spoilers do nothing on our cars.

 

Okay, so what cars do have functional stock spoilers besides the afor mentioned ones.

 

Not very many.....usually the above $75,000 ones.

 

I would imagine so. Pretty much most of the exotics right? (The sport exotics that is, no Bently's and BS cars like that)
