4" Ride Height & good ride quality?

[BANKO]

Hey guys, I would like to build a '66 Chevy II or '65 Chevelle with a 4" rocker to ground height and was pondering how to achieve a great handling car without it being a back-breaking car to drive. I have seen some pretty sweet rides being done by the top car builders in the industry and want to know how to design a properly working suspension that is not under-damped. Some guys use air bags to get this sweet looking stance. With air bags the system cost is high and the "parked" height is much different than the operating height. I would like to know what you guys have discovered in terms of suspension travel vs. ride quality. Is 3" of suspension travel even feasible on a 4" ride height car and it still be drivable for a few hundred miles in a stretch?

Thanks! Josh
