Shorter strut life > 4x4 altima
word x 10!!! phucking 4x4 factory Altima look! I hate it..
anyway, back to the OP's question... there's a reason that so many people trust Eibach. There's a suspension specialist here in San diego "the guy with the 325ix" that was winning tons of rally competitions just from doing a super supension overhaul.... anyway, his company mainly does suspension for high end sports cars, and the word out of his mouth was that "Eibach" was the only suspension company that he knew of that did their R&D the right way when it comes to building progressive spring sets.
Eibach builds there pro kits springs to be used with or without factory struts and shocks. Their Sportline sorings (not offered for our cars) are meant to be used with upgraded aftermarket struts and WILL wear down your factory struts pretty quickly (know that from experience) but that's something that Eibach will clearly let you know when purchasing them!
