Somethings I have learnt about vibs at 60-80 mph with my aftermarket wider AMG rims.....After motor mounts, transmission mount, rechecks of rim out of round fixed, multi tire choices and re balancing, a rebuilt driveshaft - re balanced, new parts and new flex joints etc......what really made a difference more than anything to cure it was wrapping the concentric lip on each wheel hub with ONE wrap of PVC electrical tape. My wheel rim supplier told me that race cars use this trick when they have vibs on their concentric rims. Apparently, above 60 mph G-forces are high enough to create a vib between 60-80 mph IF the concentric rings are slightly out of tolerance.
