I thought spoilers in general added drag?
Without a wind tunnel to test in, you're probably more likely to do harm than good with something like a spoiler, but they can help in some cases - I'm sure Honda did wind tunnel testing. Ditto with anything else you bolt or tape on which sticks out in the wind. Wings always hurt because by design they generate downforce at the expense of drag.

Pretty much the only easy, guaranteed DIY modifications are those which cover aerodynamically dirty areas with smooth panels, e.g. wheel spats, radiator blocks and belly pans.
