The C7 hub was designed to replace the C6 33 spline X Tracker hub that was so successful in the C6 ZR1 Corvette. GM decided to put in in production across the full C7 Corvette line up. For this reason mass producing it brought the price down dramatically. In this case.....the cheapest hub is also the best hub to use. Also if you are tracking the car "hard" then your wallet will thank you in the future.
