The problem is on the mk2 the discs bolt on to the rear of the hub not using the wheel studs to locate them.
Im using group 4 alloy hubs which have a larger face that the wheel bolts to, i carnt get a disc to go over from the wheel side unless i machine the hubs down which would leave the studs to close to the edge.
The discs i have are cosworth ones which are perfect size, i think im just going to machine the centers off and bite the bullet and get some bells to suit.
Unless anyone else has any ideas.
