15" wheels on a Stradale LB?

[ProtoTipo]

9mm per wheel then?

Back on topic:
Will 14" wheels fit the LB STR?
If so, Richard could go for either of the two Dino wheels. Cromodora 6.5x14" or Campagnolo ('chairs and flairs') 7.5x14".
Both of which were used on the works rally cars with gravel tyres, as seen on David Hanman's Safari car (when he hasn't got his yellow coffin spokes fitted).
Road tyres could be 205x70xR14, XWX, CN36, Blockley, or something cheaper.
