In my sale thread there is a picture of the standard springs for reference bud, might help identify it although if you jack up your car might help while doing it. I would say the front from your description and it looks less of a bend radius than the rears but hard to tell from the pictures.
Looks like part of a spring coil bud. From the looks of it either top of bottom due to the coated end, so have a look as best you can on your spring although not sure how easy it is to look at the top as I think it's fairly into your turret.
Postage would be at cost although if you sort the postage your side it would save having to pay the fees on it if you get me.
Paisley freight does it for 35 I think, trying to confirm on their site but it's not loading for some reason.
Everything is still for sale apart from the bmc filter folks.
If you want to book collection for large items I will post them but the buyer needs to book it but I'll get them all packed up and safe for transit.
Not sure tbh mate, although the standard suspension is a bit stiffer than the bc coil overs I had but I did have the coil overs on the softest setting.
If they are like the bc coil overs you need to screw the whole unit to avoid changing the spring tension.
If not as in the whole assembly can't turn, turn the locking collar to adjust the height either down or up i am guessing as not sure what they actually look like or familiar with b14 coil...
Since I have sold my twingo the following items are no longer needed!
Standard silvers tone alloys: £400
3 in very good condition apart from being filthy, one has pretty bad kerbing and not sure if all good so I will say one is a spare due to the unknown condition.
Comes with tyres, 2 are above...
