Wilwood conversion problem

ChrisPerry said

Is there enough meat on the spindle to allow you to turn it down for the correct register for the stock wheels? Seems I read somewhere that someone else did that.

It's been years since I was involved with those hubs, but I rather doubt it. I converted all of the hub p/n's in their inventory from castings to forgings. Some clearly could be made smaller on the register, but there was no point because that would have made them non-stock.

As to hub-centric vs. lug-centric; I don't see any real advantage in hub-centric. Maybe, MAYBE, if I were regularly going 200 MPH there might be a difference. At the sub 100 mph velocities that I'm bound to it's not important.

Wilwood's position at the time was that there are too many different wheels out there, stock and aftermarket, to try to make the hubs fit them all. They strived to make the hubs as close to the OE shape as was possible. I doubt that's changed. As posted in this thread there are stock wheels that don't fit stock hubs. I don't see how wilwood could correct that. As to their telling you this fits and that doesn't fit, they did in a way. They publish a drawing with the important dims. They don't know the dims of your wheels - it's simply not possible to keep track of all of the relevant dims of all of the wheels that could ever likely be used on any of their products. They give you the dims that you need to be able to decide if your wheels will fit. The idea that performance improving parts should bolt-on like they're OEM and work with everything else that isn't OEM that happens to be on the car is a bit preposterous. All of the aftermarket part mfg's strive for it as best they can, but they know it's never going to happen 100% of the time. They're lucky to get 10%
