A spoiler on a fwd car is not always for downforce. Yeah a giant wing on a fwd car puts more weight (both from the weight of the spoiler, and from the down force acted on it) on the back, and less on the front, reducing grip. However a lot of spoilers just make the car a little more slippery through the air, giving a passive, mild efficiency bonus.
