On the Extras tab of the page I posted they have Spline Drive Adapter for £360 for a set of 4. From something I saw on the electric MGB made by RBW I assumed these wheels can be put on a centre lock hub, maybe that is what the Spline Drive Adapter is.
Assuming you need to buy 4 wheels at say £180 plus the spline Drive Adapter set that is £720 plus £360 = £1080.
That works out less that these

Both seem nice but pretty expensive when you add 20% VAT as well. (When did VAT reach 20%? I think it was 17% when I last visited the UK and that seemed high)
However
