are you going to switch to coilovers D?

I am sure that you would be able to get a coilover to work, as they sell the same type of thing for light cars like clubmans, etc. You could modify the spring rate by the angle and distance along the lower swingarm.

It is interesting that the coilover is attached to the tie rod, I would have thought you would have gone to the swingarm... any thoughts?

cheers
