I cant be the only one to think of this but ive been researching miata fitment for months since i got mine and ive never seen it mentioned. Think about it, in order to clear wider and/or lower offset wheels you need to camber in. To do that you adjust the cams to bring the lower arm OUT. Seems to me like moving the bottom of the wheel out seems like an inefficient way to move the top in. By the time you get fender clearance up top the camber is insane. What if you used an adjustable upper arm to just bring the top in? I feel like you could then clear without having to run crazy camber. Has this been tried before? Does it not make enough of a difference to matter?
