Unlike most ricers, I want to find a wing for practical purposes. The rear end has always felt squirrely on high speed curves. I tried to cure it with suspension mods, but it has not fixed the problem. Ideally I would design an undertray for the car that would basically suck me to the pavement, but hey, I'm not an F1 engineer with an unlimited budget. Are there any wings, preferrably adjustable, that provide good downforce without looking tacky? Does the geniune Mugen spoiler provide any downforce?
