They are very cheep (£28 for a set of 4 with good Michelin tyres from eBay) BMW Mini 15" which I plan to make as fake Dunlops.....the expensive bit was the adaptors from the US (~£200 once I'd paid the tax which was £50).
Expensive but beautiful......aircraft grade aluminium......
They fill the arches nicely -
The roll hoops are removable (Audi TT - £10.99 inc postage on eBay for hoops and cross member) and will be covered by Sammio humps.
