Thanks for your input and advice. If I can get rid of the spacer detween disc and hub by using bells and rotors that will be a part result. I like the 7 spokes and I dont want to go down the route of changing them. I am in contact with Godspeed brakes who may well be supplying what I want. They by the way supply pistons and seals for Brembo calipers , and AMG items that are rebadged Brembos. Also, they can make items that are no longer available for example, stainless steel pistons. I will add to this post when the problem has been overcome.
