they lower about the same, so the camber wear will be about the same...anytime you lower a car you will get some camber. i have had the neuspeed sports and loved them...i think both them and eibachs are very good springs...i got rid of mine cause i wanted a bigger drop...i went with intrax (2.75"drop) and i like the ride i get with them just as much as the nuespeeds though.
if you do drop it GET NEW STRUTS. it is pointless to drop it without getting new struts...i tried to get away with just springs...and 2 days later my struts blew(this was with the sports) so a week later i had to take my suspension off AGAIN to put new struts on....do it right the first time and you will have no regrets....you are on the right track ....at least you didnt try to go the cheap way and get some apc springs or something....your suspension is the foundation of your car...dont just settle for things...do it right.:thumbup:
