VERY embarrassing progressive spring question

[k80rum]

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 ..

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 😬

Watch out, whatever hits the fan will not be distributed evenly

😬 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!

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!

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.
