The proper Ripspeed pattern ones, as sold by Mini spares, have a larger
spring platform than stock cone and thus are (reportedly) supposed to
give a better spring rate. Would your average plonker notice it? Hmm,
hard to say.

Would you have another reason for doing it (ie: adjusting ride height)
or is it just for pub bragging rights? If the latter, I would probably
just leave well enough alone.

I would also mention that you shouldn't just fit them to solve a
sagging suspension due ot worn out cones/worn thru knuckle cups problem
either. Solve those problems the right way instead.
