Hey guys, finally getting around to installing this.The question I have is I'm wondering if I can do this with my current setup. I'm using h23 axels and a m2s4 trans. Before I go an tackle this, everything should be fine assuming I'm using different axels or spacers, right? Has anyone done this recently?

EDIT: Wow what a bunch of useless info. I have the 5th gen front/rear knuckles/bearings/hubs/rotors/etc so this will work with washer or 5th gen axels, and I'm assuming it's just bolt on pretty much, also the suspension is the same is it not? By suspension I mean struts/springs.
