I live in a cold Canadian city where the road quality is best describe by the word: CRAP. If you have anything even slightly resembling a sports car, get ready for lower back pain and LOTs of suspension repair bills. What I would like to know is which 1500 suspension set up is best for where I live between a LTD with the a/s or a LTD or I guess LHorn with coils? I know both would have 22s so this is not a wheel tire question. Question is more which suspension does a better job of isolating "choppy" broken pavement and pot holes so more "jarring" medium size stuff for a city? I always thought a/s was the stiffer set up so would that not mean coils are superior in this case?
