i'm sorry, but it really depends on the person. I've ridden on shock/spring combos and i've ridden on a nice coil-over set-up. but i could really care less how the ride was. the stock suspension on my car now is a little bit better than the skunk2 pros on my integra and that's not saying much. forcing your opinion on how a car's ride needs to be should just stay advice, not commands.
if he wants a good quality ride, he may take the advice on the shock/spring combo. if he wants to slam it, he'll probably just ignore your "commands"
