i think that the cossie springs are rated higher but are shorter while the 4i springs are ongers but softer
does that makes sense?

the spring rate for the cossie is (from memory) 140lb/in and the one for the 4i is (again, from memory) 105lb/in
but the cossie spring is shorter so that it won't compress as much
the 4i spring is longer but softer so it will compress more but it should be the same ride height
as someone who knows a tad more than me about what this will do you'll probably find that the cossie springs will firm up the ride in the 4i but it may sit a bit lower than normal overall
but the cossie spring is shorter so that it won't compress as much
the 4i spring is longer but softer so it will compress more but it should be the same ride height

. I just don't want the cars to sit too low and for the springs to be overworking the dampers by being possibly too short .I was hoping that you would say the actual damper lengths that the sprongs sit in are identical
, that would make me VERY happy .Many thanks for taking the time to post

). This maybe the way to go if the height isn't right .

. )the 4wd springs are margianly different again to the 2wd cars but i'm not sure how much sfitter they wuld be as they have to support the extra weight
which V8 is it under the bonnet? if it's a rover they tend to be the same sort of wieght as the cossie anyway
but if it's one of the other forign imports then it's a case of trial and eror
