but a wing only works at hi speeds...based on the airplane principle or hydrofoil is u wanna call it......n i havent heard of peeps racing in the snow....or going fast nuff for the spoiler to work.......on a front wheel drive car it is ideal to have a sleek small spoiler like a jetta factory spoiler or a civic or rsx factory spoiler.....but on a rear wheel u need a big ass 1 like an F1 spoiler(not so ideal for FWD)
