I don't have issues with stability, but the ride is rough to say the least. I know it will never ride like a diesel chassis, but there must be a way to soften the ride. I'm thinking about adding sumo springs to help with the ride. Has anybody had any experience with adding sumo springs and if so what were your results? Good? Bad? Save your money? At approx. $1200 this isn't a cheap upgrade. Thanks for responses.
