k80rum Posted August 24, 2007 Posted August 24, 2007 My progressive rear springs have coils close together at one end and more widely spaced at the other. Which way up should they sit on the damper? I've just noticed in a picture of someone else's car, the closer coils at the bottom. Mine have always been uppermost on the damper. See, i told you it was ..

Dickie Normuss Posted August 24, 2007 Posted August 24, 2007 It shouldn't make any difference to the spring which way up you put it. It might help to lower the cars centre of gravity by having the more spaced coils at the top 😬 VX HPC - Loud and proud here Watch out, whatever hits the fan will not be distributed evenly
k80rum Posted August 24, 2007 Author Posted August 24, 2007 😬 so that's why it rolls so much Cheers Ric. I wondered whether it'd make any difference in conjunction with the damper but i guess none if any. Phew, at least that's one less job for the weekend!

Claire Voyant Posted August 24, 2007 Posted August 24, 2007 K80/Darren Not neccesarily . The same question went through my mind about the spring/damper combined unit. My brain tells me that it should make no difference (unless it fouls something) but there is this little voice of doubt (the Ben Elton "Captain Paranoia") which asks "Then why were they always mounted the same way - until a few people all started putting them in upside down?" And the answer is:- of course it makes no difference, but just for the sake of neatness, always make both sides the same!
Colin Mill Posted August 24, 2007 Posted August 24, 2007 A minor consideration is the unsprung weight. By putting the light bit to the unsprung end you will slightly reduce the effective unsprung weight. Unfortunately this goes the other way to the Cof G argument but my guess is that it has a bigger fractional effect on the unsprung weight than it does on the C of G.
