I know coilsprings aren't ideal, most don't have the rising spring rate :P but atm I d use anything to be able to finaly drive the damn thing :P

then just get some donuts and then you wont need to change them later.
I would, If I could get cones as cheap as the coils i can get

I am an avid supporter of coil springs but cheap and coils does not go together, I only know about minitastic springs and would consider no other unless a good reason was put forward. Sounds to me you need rubber donuts as that is the cheapest option.

I have never been able to see any advantage with coil springs.

AS has been pointed out many times by many contributors, the Mini has very short travel suspension and, therefore, needs a non-linear rising rate spring. The rubber cone was specifically designed to do this job and is absolutely ideal.

The only time a coil will be better is for racing where a much higher initial rate is needed to reduce body roll at turn in. 

No coil spring can improve on the original concept due to the limitations of the basic suspension design.

If a softer ride is wanted, then get adjustable dampers and set then as soft as possible.

The limitation is the amount of total suspension travel which must be controlled by the spring. The spring must not bottom out at full travel if it's a coil spring and must have the correct pre-load when on full rebound. The rubber cone spring does EXACTLY that as it's what it was designed for.

I wonder why it is used? And no longer used by the seller?

I know Theyre not ideal,but its a 60 quid difference for me (+ no postage). Its not about the softer ride, just about the money atm, after being screwed over by a machine shop, writing off a crank and conrods I really need to save a bit where I can.
The seller is selling them because he 's going to try the fast road springs instead

Dusty, try them. You can always on sell them, but just as some of the other guys like them, you might find the same.

 

Gotta try some of these things.

 

And given you're down to your last few shekels, they seem not a bad price.

Gotta say, i haven't run on rubber cones for 20 years.  used to run on cones before I had a 20 year lapse from minis and they were on mk1's and 2's in the eighties so likely were a bit shot anyway.  I bought my clubby estate with springs already fitted.  maybe it's me and my rose-tinted spectacles but it doesn't half handle!  Really flat and precise, the missus is on the verge of liking the car since I rebuilt the engine too!  I don't know what make my springs are - when I questioned Minitastic he denied they were his though they (the trumpets) look the same.  Dusky, I know it doesn't tell you much but you might be pleasantly surprised :-)
