Then why do manufacturers put them on front wheel drive cars? They obviously must test the cars out in wind tunnels and can see that a spoiler pulls weight off the front end. Or do the small factory spoilers you see on alot of cars dont do much? Do the high wing OEM ones cause alot of downforce in the rear?

 

Most of them, you'd have to be going faster than the hamsters can push the car to get any down force. Mostly they are either aesthetic or they serve to break up the vortex on the back of the car for lower cd.

 

Yeah there mostly for looks and maybe a small improvement on some cars (evo/sti), real wings can have 100+ lbs of down force at 80mph, that would really screw up the handling without a big splitter.

 

The Tiburon's is actually facing slightly upwards. No downforce there, pure upforce.
