I've done a search and couldn't find any definitive answer...

Are Springs the same accross the One/MC/MCS range and only vary slightly in firmness depending on the car's weight/optional equipment?

If anyone could confirm this I would really appreciate it.

Thanks!

i was under the impression that there was standard suspension, sports suspension and sports suspension plus.

Each one is a little stiffer and a little lower than the previous version.

Someone correct me if i'm wrong

Benmk is correct but there are also spring variences depending upon what equipment you had in your car.

I was told there is a points scoring system for each option as it adds weight and depending on the score depends which springs they opt for. So S, SS and SS+ have a number of spring options depending on your er.. options.

Thanks for the replies.

I just want to add that I am only referring here to "springs" as opposed to struts/shocks which indeed differ in stiffness between S/SS & SS+.

What I am trying to verify is whether the springs are the same accross the range and only vary depending on each car's equipment/options (weightwise).

I am asking this because I have installed the SS+ spring + shocks from a Cooper S onto my One and only realised later that maybe I should have just swapped the shocks and keep my old springs as the springs corresponded to my car's weight and the new ones correspond to a heavier Cooper S.... see what I mean? This would only make sense if the springs are the same accross the range, i.e. One Springs fit on Cooper S shocks, which is what I am trying to assertain.

Could anyone confirm this? Maybe someone with access to ETK.

Many thanks!!

The springs are not the same across the range. There are specific groups of springs for each of the suspension options otherwise all models would have the same ride height. There is however only one set of dampers per suspension option.

Here's the poop on which springs are supposed to be on which models for
European 8/02 cars.



Front
one without ss
31336759337 -338 or -339
one with ss
31336759382 -383 or -384
cooper with ss
31336759382 -383 or -384 (same as one with ss)
cooper with ss+
31336759387 or -388
MCS
38336759388 or -389 (overlaps with MC/SS+ for the middle value).

Rear
one without ss
33536756652 -653 or -654
one with ss
33536756657 -658 or -659
cooper with ss
33536756657 -658 or -659
cooper with ss+
33536758354 -355 or -356
MCS
33536758356 or -379 (overlaps with MC/SS+ for the middle one).

So, for each of the suspensions there are three springs
which depend on vehicle weight.

but for the MC/SS+ and MCS(also SS+),
the first two apply to the MC and the second two of the three
apply to the MCS.

Your car would have -337 front (pink)and -652 rear (brown) without ss

or -382 front -657 rear with ss

or -387 front -354 rear with ss+

for the stock ride height and spring rate match.

I get some different numbers for my USA 3/03 MC
I'll post a summary in a bit.

looks like the difference for USA 3/03 models is:
the MC with SS+ has different rear springs
33536763282 -283 or -284

also, the MC with SS has only
335367763280 or
335367756659
rear springs.
the fronts for MC/SS, MC/SS+, and MCS, and the Rears for the MCS
are the same as the previous post.

My car should have the 33536758283 rear (two grey stripes)
and 38336759387 front springs (2 purple stripes)

Thank you for the thorough reply, Cristo! I am very grateful.

Just wondering, about the cooper with ss+ and MCS Front springs reference numbers, there are only two instead of three, is that normal? Same for Rear MCS springs, only two...

Regarding my car (One) with SS+ which is not a factory option, you based the results on the Cooper with SS+ I assume, so -387 front and -354 rear springs is what I should really have in order to keep the stock ride height and spring rate match according to my car's weight, correct?

This gets a little complicated.
For the Euro models I looked at, there are actually 3 front springs for SS+
the first two are for Coopers and the 2nd and 3rd are for Cooper S models.
There are actually 4 rear springs for SS+
the first three are for Coopers and the 3rd and 4th are for Cooper S models.

For my USA model the fronts are the same but
the rear SS+ springs are one of three possibilities for the Cooper
(different than the Euro part numbers)
and one of two (same as the Euro numbers) for the Cooper S.
I have no idea why.

The table suggests to me that yes, the appropriate springs to make a one with SS+
would indeed be 31336759387 front and 33536758356 rear,
along with the SS+ struts and the SS+ swaybars.

Of course, by now, maybe these part numbers have been superceded by new numbers,
as parts departments like to do.

in my visit to HK, I was driven in 3 different MINIs
but found the MC fitted with the SACHS adjustable absorbers/ springs ride comfortable.

Just wondering if anyone is using the SACHS adjustable absorbers and care to share as I am thinking of fixing in my ONE.

CHEERS!

Does anyone know the length of 33536756657 and 31336759382? I'm planning on buying KYB k-flex which are 261 mm / 260 mm on the front and rear.

Right now my cuurent springs are 261 mm rear and 225 mm front but I don't like the lower front.
