To take it a step further, how much of what we do in this hobby is "necessary"? The budget angle is one angle, and it is the one I choose. But I respect the hell out of someone who can completely re-design a suspension to work better, regardless of cost. Hell, they might be doing it just cuz it looks cool. More power to 'em. It's really no different than building 600hp motors for the street. We don't "need" that, and we probably doubled the cost on the last 150hp. Who cares? We're having fun! Also, at my age and experience, I don't like being talked down to, and I hate self promotion. Form your own opinions from there.
