The softline RS 7 Spokes are ET38 mm and to fit them to my saf 4x4 i had to fit 3mm spacer shims on the front two wheels to allow the alloys to clear the brake calipers. If as you say the Diamond cut versions are ET 35 mm then i would suggest that you would need 5mm spacer plates on the front hubs. They definately fit on saffs because plenty of boys have them
