Ha, Greg, those are my thoughts exactly. This thread is one of my favorites in awhile and I am trying to "hang on by a thread" with all of this tech.

Hey Blake - understand the why of the SKF hub and like it. But...on the fronts they do require replacement after a certain amount of track time. Do you think the rear wear and tear would be about the same MTBF?

Anyone know what the Australian Supercars Ford rear ends are using? They might be a better comparison to PT applications than NASCAR. They definitely get abused and turn left and right. :D

Note - It looks like they may be switching to IRS in 2013.

From what i understand???? which isn't much sometimes lol the SKF ZR1 hub was designed for the ZR1 and for racing. it is much heavier duty than the C6 Z06 hub. the Z06 hub is the same as the standard C6 and that is what we use on the AFX Spindles ( it is what EVERYONE uses that supplies Corvette spindles on their suspension packages)

people keep talking about having to replace the hubs but we have never had anyone call asking or questioning or complaining about worn hubs??? yet


My nova has some hard miles on it with no issues as of yet. i think if a guy was going to the extent of a floater rear he would also upgrade to the ZR1 hubs in the front if he has AFX or Corvette spindles. they are in the 400.oo each range. the SKF Racing Hub is just a ZR1 factory hub no differance there.

Just to expand on something "ccracin" touched on. Floating axles are not new and in fact are run 100s of MILLIONS of hiway miles every year. Every truck you see 3/4ton and up is equipped with floaters. Every class 8 semi-truck you see running down the hiway is equipped with floaters and most are equipped with aluminum hubs. There is no magic about the floating axle design, it is no different than a two bearing front spindle on say an older 4x4 jeep or pickup. The current generation of 4x4 and front wheel drive cars/trucks is another example of a floating axle design with sealed bearings. There is a reason that circle track racers and off road racers adopted the floating axle design to their application. Simply stated, floaters are stronger than bearing on axle rear ends. Why you ask do manufacturers still provide bearing on axle rear ends? The answer is simple, cost. The bottom line is, regardless of the manufacturer, the floating axle design is far superior to bearing on axle designs.

I have run the same parts store c6 hubs for 2 years racing wheel to wheel, we check them but have not had to replace them.
In fact vinnys red car (my old shop car) has the same bearings in it that it had a motorstate in 09

I've got 6500 street miles and 20 races or better on mine. Still nice and tight. They are engineered for a corvette after all. :D

Here's a good question. What's on the C6R?

Thanks Jake. The Corvette guys quickly found the stock c6 hubs wore out after one season. If the SKF/ZR1 hubs last a long time than that's good news for Blake's product...:thumbsup:

Edit: The Vette 'may' pull a few more Gs than we do, or submit them to more hours which could cause explain a shorter life span.

Good point Ron. Let's keep in mind that this is a pro touring website. 99.9% of us aren't putting Z06 Corvette with road racing slicks load on thes cars, EVER. On top of that, we aren't putting daily driver miles on them either. ZR1 hubs should last the cars lifetime. Regular hubs may as well. Jake or I will let you guys know. :D I'd be interested to hear DSE or Finch on this subject. Rttc here we come.

I will have this new Floater set up in ResurreXion for RTTC and i will also have one on display, if any one is interested i can probably get a couple more done by then and deliver them as well.
