I am not as familiar with the early Series as the later, is the only difference between the early and late rotors the OD?
Last statement appears correct. I haven't found any other difference than the OD ( early 240mm, vs late 250mm ) on the repros which I have. Comparison with some NOS ones brings the same result. On my S2 I found very thin ones but would attribute that to wear. Anyhow that means late ones could be turned down on a lathe to make them fit for early series

P.S. Top one is for early Series...
I thought they were the same.
I guess I need to revert to the parts manual
Perhaps it's just the picture, but your lower wheel stud looks out of true. Would also carefully inspect the hub whether it's rotating evenly, especially the surface where the rotor is attached to. Are the wheel bearings Ok and properly adjusted ? Wheel studs firm in the bore and true ?I agree with symptoms but not with data. .005 runout on left / .45" thickness, .003 on right / .425" thickness.
