forget all that mumbo jumbo. a spoiler is designed like an upside down airplane wing. instead of creating lift up it pushes you down. you need to be a pretty fast speed to get a significant amount of force (airplanes don't take off at 35 mph do they?)... they work alright, everything said in the above posts are correct.
venting the top of the hood? no, i don't think it will reduce lift as much as it will increase wind resistance.
