Rota kyusha wheels

I have just purchased a set of 7x15 Rota Kyusha et38 wheels to fit a 91 clipper. 

These won't fit either the front or rear. At the front they won't bolt up as will foul with the caliper and at the rear the hub bore is to greater  diameter, well I can get the spigot on to a point then the wheel fouls on the centre of drum which has a diameter of about 70mm.

Has anyone else had issues?? I gave the full description to the supplier on car and age. 

You got updated brakes on the front?

I don't get what you mean on the rear. 

Hi, not as far as I know, thought everything was standard with exception that it has been fitted with John Brown Alloys. 

At the rear the wheel won't go back to the face of the drum, it fouls on the internal diameter of the wheel being smaller than the the drum centre diameter which appears to be circa 70mm, the internal aperture of the wheel is about 65mm diameter…the JBW have a larger diameter than the Rotas.
