Making a wheel hub
I see where the Chevy guys are cutting the rotor off a brake rotor to use just the hub to mount 2 piece hat and rotors to get the dimensions they are looking for, has anyone tried this on an Granada rotor, I can’t find the hubs from a front drum brake car. If I did this mod I thought I could put a couple gussets between the lug flange and bearing hub for added strength, and I am running 15” wheels. I know Wilwood sells this setup for the M2 but it’s costly and where is the fun in that? But maybe the Chevy rotors are more beefy. Any advise is appreciated.

I can’t see what this would not work, it’s just a hub with a built in rotor, so remove the rotor. I would do a bunch of measuring on the rotor you want to use, can the remaining hub be turned to the correct size to accept the rotor hat and center it? Will the rotor be slipped over or mounted to the back like some of the old British stuff? Again, I think it is worth a try.

The rotor hub that the lugs come through is about the same diameter as the hat ID 5.83”land I can mount the new disc on either side of the hat depending on how it lines up with the caliper

The ones made by Wilwood are either billet aircraft aluminum, or a steel forging. A standard off-the-shelf rotor is cast iron....probably made in China.
It is one thing when it is integral, but you are putting together pieces, so it is nowhere near as strong. I would be a bit concerned if I was cranking around a corner with that set-up. |
Go-ogle "mac tilton on top hats for brake rotors". Images and also the write ups.
This is inspiring. |
Why?
As said above, stock replacement parts are cast iron. Cutting and welding on cast iron requires some special tools and skills. It's sketchy at best. "mac tilton on top hats for brake rotors" I did a search on this, and didn't find anything. " cutting the rotor off a brake rotor to use just the hub to mount 2 piece hat and rotors" I'm having a hard time imagining what this would look like? Do they use the center part of the rotor, and modify that to use as a hat? Or do they attach the new hat/rotor assembly to the cast iron hub? And why would you do that? Precision center hats are available for just about everything with wheels. I'm not trying to be an ass. I'v never heard of this, and I'm curious. |
Bobcowan, you’re not being an ass. I was looking at it from a cost bases, less the lathe turning it would cost about $100. You would turn the rotor down so it just fits into the new hat, so you would have a hub like front drum brakes, original lugs go through the new hat and retain the tapered wheel bearings, I didn’t consider welding cast iron but I have a professional welder I would consult about that if it’s even needed. I did a search and the Chevy and corvette guys are doing it but using a 1 piece OEM rotor over their turned down rotor/hub to get the diameter they are seeking which if I could find one with the correct diameter and offset I would too. It just occurred to me maybe you’re not familiar with Mustang ll which uses a rotor/ hub combo.

I see! very clever. Thanx for the education. :)

If you go to Coleman Racing Products....they will make any size hat to fit any rotor you want or have....
