Spoiler vs Splitter, what's the difference ??

[Balance_Point]

I'm thinking of doing a splitter against the bottom of the front bumper on my '57 Chevy. It isn't going to be a track car, so I won't make an effort to get it down against the ground or anything that radical. With those big, cow-catcher front bumpers that curve under, what are the odds that such a splitter would keep enough air from flowing under the car to reduce lift at speed?

Splitters loose effectiveness the furhter from the ground they get. So if your 57 is low enough, and the splitter tray is long (forward) enough, it should work.
