Ya I wouldn't do ebay for this piece. This last thing I am looking for now is low price. This isn't the part to save money on. The price range on corvette hubs tells you something, doesn't it. Something like $19.95 to $500.
I used (myraceshop), the link you posted, for the rear stub axles on my GTM (C5/6 rear hub). I also used their axles. The appeal for me was the stub axle which allowed me to mount the outer cv joint independent of the axle. Then use an axle with the same splines on both sides making replacements less expensive. Works great but just street mileage so far.
It gets confusing because GM sold the Z06 and I think the Grand Sport with the "big brake" carbon ceramic brakes as an option. It would be best to go to a GM dealer parts department to sort it out. All of those hubs look identical in external dimension. It's the internals that are better on the ZR1 only hub. I do know that the part number I mentioned is the exact part to ask for.Ken,
What is the difference between ACDelco FW371 and RW20131? Rockauto has them both listed for the ZR1 (I'm looking at 2010) and for the same suspension options.
The C4 hubs are different front to back. They would have only worked in the front Howard.Ken I called Strano performance 4-12-13. They don't have any more of the hoosier performance type that can be rebuilt. They would have been the answer. Four of those type all the way around.
See if Fran's interested in doing that. If not, I can have the center section made as long as I have a loaner to work from.The X Tracker hubs will not fit on the rear uprights (the bolt patterns are slightly different). The rear uprights only fit a C4 rear hub. New uprights would need to made to accommodate the X Tracker hub unfortunately.
Perhaps Fran could design a new center section to the upright and we reuse the top, bottom and toe arm portions. The differences between the C4 and C6 rear hubs are very subtle. They look almost identical but the bolt pattern is slightly different. The offset is different as well.
