so the rears are almost identical, what about the valving on these, which is stiffer/softer? I'm thinking I might get the maxima ones b/c those are prolly easier to obtain then the primera ones. Maxima ones will work with standard springs though right? for some reason I think they wont b/c the spring perch could be a different width then the primera ones. If not i prolly just get the primera ones

thanx for your all your help.
