my first post , ive been lurking for a few days , great informative site . maybe this should be in suspension but the question is a technical one . i just bought my first honda , a super clean cb7 w/ only 71k . although i'm typically a performance junkie that messes w/ everything and everything , and there is all kinds of things available for this unit , it's just a daily driver not a race car . i'm not looking to drop my car at all but i do need more spring rate , especially in the rear . do the coupes , 4dr's , and wagons use different rates and do you know what they are ? i will be replacing the struts/shocks w/ kyb gr2's and if i can grab some springs from the boneyard and throw them in while i am there , it would be great . maybe from a different year/model honda ?
