Hub for Slip On Rotor
What options are available for a hub for 72 C10? I would like to use 2018 Durango 350mm rotors with a center bore of 2.83". I know of 3 options for hubs on the market but none of them quite fit my needs:
-Wilwood C10 ProSpindle with bolt on hub/bearing: requires 3.06" center bore -Kore3: requires 3.06" center bore -Machine stock c10 rotor into a "hub": will increase track width and limit front tire size further or require large back spacing Are there other options available that I am missing. I don't want to machine the Duango rotors and don't want to increase track width. Thanks in advance. |

Re: Hub for Slip On Rotor
Could you machine the Durango discs center bore larger to match either the Wilwood or Kore 3 hubs?

Re: Hub for Slip On Rotor
I may have to. I have seen jigs for sale that you can drill new bolt patterns but i don't know how to open up center bore at home without a lathe or mill. Any ideas?

Re: Hub for Slip On Rotor
If you were careful you could use a die grinder and slowly open up the ID. You are not talking much. 2.83 to 3.06. .23 is not much. I would certainly give it a try.
But any good machine shop could do this in a few minutes per rotor once they got it set up. Maybe have the machine shop drill the new bolt pattern also? One more thought. Give Tobin a call and see if he would have hub turned down to 2.83 and re-drill for your bolt pattern. That way your Durango rotor would stay stock in case it needed to be replaced. I bought some brake parts from Tobin over the years and he has always been spot on and willing to help. |

Just to be clear though: the Durango rotor is already 5x5 so all I would need is the center bore to match and I would be set |

Re: Hub for Slip On Rotor
Time to break out the die grinder and grind away.

Re: Hub for Slip On Rotor
I have emailed Tobin and it sounds like he is willing to make the large bolt pattern hub with a reduced center pilot diameter, but it will be pretty long lead time and a costly option given that it isn't a standard offering.

Another option I found is this: https://www.lowes.com/pd/Drill-Ameri...Saw/1001326800 I'm trying to conceive how to center the hole saw on the rotor accurately and I may give this a try. Expensive bit, but I could always modify my own parts store rotors with a jig and hand drill pretty inexpensively. This option would work for the rears as well and I wouldn't have to have the pilot diameter turned down on the axles either. |

Re: Hub for Slip On Rotor
I was thinking a vertical mill. Unless the inside or out side of the rotor hat is machined the lathe would struggle to find to true center. Not saying it can't be done.
On a mill you could clamp the rotor down and find the center line of the rotor opening with a dial indicator. Then just run a fly cutter bit to open the bore just enough so it slides over the spindle. Give the machine shop the hub to check for clearance. Just my .02. |
