yes, some fwd cars do benefit from a wing.. at about 105mph, the rear of my crx gets a little twitchy. after i installed the wing it smoothed it out a lot..
and before anyone here bitches, the crx looks basically stock. i roll 16" double-7's and the wing is an edm (european domestic market) lip spoiler..
i drive a honda, but i hate ricers that give everyone else a bad rep.. i know the limits of my car, and ricers do not..
