Measured this spacer's width and made a new, wider one, that brought the axle flange end play down to ~0.001". Figured it would be good to allow some running clearance for heat expansion and to avoid bearing preload. I have yet to drive it but I have 7/8" manual master and 4piston fixed Dynalites in the back, hoping to test out within the next couple weeks. Not sure if this is helpful for you Torino-bearing'd guys but simply an idea.

I'm not a metallurgist - but allowing for only .001" growth in axle length (figuring 20+ inches?) certainly doesn't allow for much heat expansion. :wow:

A couple of comments that I can make with a fair bit of certainty... since I've had hands on experience...

• The Pfadt Racing Hubs are exactly the same as the the SKF hubs - there is no difference. They are simply doing a better marketing job.
  
• The SKF Racing hubs are materially different from the stock Corvette (i.e. non-ZR1) hubs. There are additional bearings (on the (in the?) outside shoulder) and the shoulder itself is larger diameter to accommodate the additional bearings and improve the pressure base.
  
• While the materials used in the SKF and stock bearings may be the same (I can't prove it one way or another) I believe that the process is different - the SKF hubs are visibly different.

While I understand the desire to be thorough in looking at a "new" product - I really can't understand why the SKF bearing would be the part in question. I think that it is safe to say that it is the least unknown or unproven commodity here.

I have to hand it to Tom and Blake and co. for designing a system which takes advantage of a reliable, street and track proven component and adapting to to "our" applications.

James, you will most likely have yours in and running before I do. Lots of folks have already asked me for feedback as soon as that is possible---so let's agree that we will come back here and post that feedback in this thread (if it's not locked by then) for future consumers to assist in real seat of the pants and actual performance/impressions. Durability will prove itself over time, and since we both attend many events and drive the cars quite a bit, we should also be able to provide that piece as well in the future.

See you at RTTC---Taco cart and Apple Pie have been secured.
