I don't know as I buy that theory or not, but not being a fan of coil overs, I guess that can be expected. When I was in the car building business, I built what the customer wanted, and probably 75% were coilover, and the customers were happy, I, myself have always ran a 4 bar car, and the way I build them, I don't have a problem with the bars being a disadvantage, I can chg my fronts in 20lb increments in a flash, don't even need to jack it up, I can change each corner a total of 100#, either add, or take off, plus, it to me is a lot cheaper, in the long run, tag a marker tire, or another car, and the chances are good you'll be replacing a shock, maybe a spring, and hunting the rest of the stuff that gets lost in that sort of stuff. Coils vs bars have been a thing of the week since forever, if someone showed up with a cross leaf front, and won, you can bet your begonias that next week, at least half the cars would be sporting a cross leaf front end, just like they used to say about Kinser, and the dog turd on his hood. To each his own, I see no reason to take a perfectly good handling car, and chg it. The gentleman that gave Stewart his start, liked to mess with them, one time he'd have his ladder heim on the chassis, couple months later, the other way, and everyone had one of each in their trailer, didn't know why, but they had one! JMHO Bob!
