Here's is what SKF says about them:
"Racing cars require exceptional cornering performance and stability, which rely on a high-performance wheel bearing unit.
 
Our version, called X-tracker, has a double row angular contact ball bearing arrangement. The outboard row has a larger diameter and contains more balls than the inboard row. Its asymmetric design increases load carrying capacity and operational life and raises camber stiffness above that of symmetrical hub units.
 
Improving camber stiffness allows the brake rotor to tilt less during cornering, which reduces brake calliper piston knock back. This allows the driver to brake later and reduce lap times on the track. The small inner ring is retained with orbital forming, so the bearing will stay in preload under heavier loading, for a longer service life."

FITMENT NOTE:  From 1997-2008 GM used 30 Spline hubs.  During the 2009 Model year GM started to upgrade all cars to the C6 Z06/ ZR1 33 Spline hubs.  If you have a 2009 NON-Z06 or 2009 NON-ZR1 Corvette you will need to pull the hubs off and count the splines to ensure you are ordering the correct hubs.  If you have a C6 Z06 or ZR1 you will need to order the 33 Spline Version
