Machining drums to be used as hubs?
I recall a thread where someone machined down the drums (with 5x130 pattern) to fit inside or on top of a Porsche rotor to be used as a hub. What's the feasibility of this?

Better bet would be to machine down aftermarket Porsche pattern discs, they have the strength in thickness then and you could fit studs.

When you say Porsche discs, are you referring to VW disc brakes with the Porsche pattern? And are they available for the rear that way?

Yes, I was talking about Porsche 'bolt pattern' discs for a VW, they are thicker around the mounting area. Porsche made the rear hubs already (they are on the 944 )

Thanks ricola,
One of my goals is to keep possible width increases to a minimum... Ghia you know. My figurations are / were that I would only (possibly) get <10mm increase per side which would be a good thing for those of us who are a little lacking in wheel well space... Ghia you know Anyway, I figured that would be a good way to not widen things too much. I've got some early 944 aluminum trailing arms with all the necessary components to mount them on my Ghia, as well as the front hub that needs to me modded to work (later style for the front hub), I've just got doubts about the 'relative ease' of making it all work... Ghia you know DORIGTT |

Hi
You could use stock 4 stud drums instead of discs and do the same thing, the disc will give a slight track increase of the drum. If you then studded the brake drum to 5x130 that would work. On my old 1302 I used 5x130 bug discs with the braking surface removed, then bolted the Porsche rotor on the back with a spacer to get the offset correct in the same manner that Porsche rotors fit up.

How well did that method work for you?

Hi
They worked fine, I will be using them on my next car as well. Steve

Why not just go with the CB chromoly hubs? (from their race strength disc brake kit)
BTDT on machining down some drums. That cast iron is hard material, requires carbide tooling. A lot of work involved, you have to make a good fitting mandrel to hold-em while machining, lots of cutting and machining time, etc. If you were paying someone to do the work you'd likely be much $$ ahead getting the CB hubs.

I just looked at their website per your suggestion and didn't see any front hubs as you mentioned.

Oops, didn't seen any specific references to front hubs.
I was referring to the rear CB hubs. I think the only aftermarket front VW hubs I've seen are Vdub Engineering and Airkewld. |

Hi Skeeter
You could use Type 3 rear drum centres for that, or buy some 5x130 rear drums or another thing I looked at was cutting the back of the steel arm 944 flange down to narrow the track, you would end up with less spline area, I'm not sure how that would go with high horse power. Steve
