spoiler doesn't give you downforce. it reduces your drag (air resistance) profile. You need a real function wing. Doesn't necessarily mean you have to get an obnoxious one. But the best way to know if a wing works is to aerodynamically test it in a wind tunnel. Alot of the wings out there are bullshit. they do nothing more than cause drag and slow you down.



Why 3500 miles?
