I put the front cones on first, and it looked like the nose was up in the air, it didn't come down much over about 3 months (even though my Mini only goes out on sunny days) so I replaced the back ones also, this evened height it up nicely, it now rides lovely, little bouncy but much more comfortable and smooth than the banging along it used to do.(replaced shockers and all tyres). i stuck with the cones as am keeping car total BMC spec/original.
