never heard of them, so it can't be a great thing. If you want them, ask those guys if they make any that fit the Altima. If not, hey, they're free right? Get a set anyway and see if they fit. If not, sell them to a Civic owner (like Sam21

)
EDIT* Just checked a site that lists them, they don't have any of their springs available for the Altima, just Maximas and Sentras. And lots of Hondas. Like I said, sell them to someone whose car is listed here:

They don't seem like top quality springs to me.
