Began with i3/8 and all CLAR based cars (G11/30 and newer). It saves a tremendous amount of weight in the axles and wheels.
No previous gen wheels are compatible for 5/7er.

is there any difference between 66.5 and 66.6 for the CB? And do you know the offset number?

Supplier tolerance requirements and method of rounding to the nearest 1/10mm. I just recently divested my ownership in a Tier 1 wheel supplier a few weeks ago and our engineering was to 66.56 with a +/- 0.02mm tolerance. My recommendation would be to apply a light coating of lithium grease as the CB's that are tight (66.5-66.56) can be a PITA to remove sometimes.
Offset is dependent on the wheel dimensions. For aftermarket, engine, drivetrain, and suspension options can have different clearances on the Gxx cars.
