Am I right in thinking the Cloverleaf alloys are magnesium rather than aluminium?
I have to say, mine have been very resilient to pothole damage, but the awful tyre roar was hurting my ears so as an experiment I got some old 16" Alfa pepperpots, refurbed and fitted with Dunlop SportMaxx. Immediately apparent are: loads more comfort, the tyre roar has disappeared to well below the wind noise, and the handling's actually not too bad at all. And I have coilovers and drive pretty lustily.
The roads round here (and apparently elsewhere in the UK) are appalling, I think I'll stick with them for the time being.
