The Bearings are Direct from General Motors, and are the NEW Corvette Front bearing they are NOT splined like the last version which used the same hub front and rear. they also do NOT have wheel speed sensors as GM is obviously using a different system on the new Model.
The bearing pack is larger than the previous hub as MFAIN mentioned we need to machine the WMS and spot face the mounting surface to install the bolt this was not required on the last models The WMS flange is also approx 30% thicker than in the past.
The bearing packs have the same offset as previous versions same hub diameter and same wheel studs they now have a rubber seal on the back side I presume to keep dirt from between the hub and upright.
