Well there's some centre lock ex BTCC wheels for sale on a RS spares website and they're 16s and centre lock?
The person in question with the Mondeo Dymags is on here as well, Percybigun. I found them on eBay, genuine wheels, came of a 3 dr and he has them on his Mk1 Mondeo turbo. They've been drilled to 4x108 fitment, pics here if you've time to scroll through
