well then that would make you one of very few. i've talked to a lot of folks who have done this on their mustangs, vettes, subarus, imports, etc and they all say the same thing: yeah i have to drive it carefully but its a sacrifice for the look. or they have another suspension/wheel/tire setup they use for actual driving and the "stanced" one just for a show. either way, the car doesn't perform as set up.
not to mention i have heard *plenty* of stories about all the ghetto "clearancing" people do to run this kinda stuff. notching a-arms, running big spacers, bizarre steering and suspension geometry, trimming fender lips with a sawzall... and of course the related stories about car wrecks, cut tires, bent wheels, cracked wheels, and bad driving manners in turning and handling anything less than perfect roads. running so much camber on a tire that's not being fit properly to a suspension thats compromised to ghetto engineered steering geometry doesn't seem like a good idea on paper, and its even worse that people would drive something like that in real life.
besides, common sense tells you all you need to know about performance when you see wheel and tire setups like these. where does the wheel go when the suspension flexes? where does the tire go when the steering wheel turns?
