what do you mean by bouncy .?
I have a textbook "rough ride", 20" lowered . I've never gotten a complaint of a rough ride from my older folks, (mom, grandma, dad) . Yes its somewhat stiff, but I rather have this setup than the stock "floating ride"
my question was rhetorical , the altima doesnt have the same effect as the mid 90 civics that bounced around with cheap springs. I think the R&Din' on spring have gotten much better now.
