Machining drums to be used as hubs?

[Steve C]

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?

[Steve C]

Hi

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

Cool, thanks.

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.

[GS guy]

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.

Steve ,your a genious .I reckon i am going to nick your idea for the back of my bug as the 944 rears are way to widefor my 66, but reckon i can use either the carriers or a beetle drum to keep the stock offset.sorry to crash your thread Dorigtt

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.

I have also done something similar.....on the front of a type 3, i used the front discs with 5x100 bolt pattern then machined off the brakesurface so they would fit in a rotor from a 2001 jetta 2.0 then fabbed up brackets and used a caliper from a 96 jetta 2.0 and voila........bigger brakes w/floating calipers using al stock vw parts! (except for the custom bracket) http://www.franklinsvwwerks.com/phpb...760&highlight=

hey guys,
would this work?

if i used a stock vw 4 stud disk or drum machined down to use as a hub with a porker vented disk, then have the 4 stud vw pattern put into the disks. a early 944 caliper and mounting bracket.

i want to keep 15" vw pattern wheels...

cheers

Hey Mabbo,

I've got a set of early single-piston sliding calipers if you're interested.

[mabbo]

hey dorigtt
i guess the postage from america would be a fortune, im in the uk so would probrally be easier/cheaper to get some from over here...
cheers for the offer though.

can anyone see why this wouldnt work?

vw 4 stud drum or disk machined down to use as a hub
get a 944 disk re-drilled to 4 stud vw pattern
bolt the 944 disk up to the back of the "hub" like Steve C's method
regular 944 mounting bracket and single slider caliper

this should give me vented disks and still use vw 4 stud wheels?

Steve your set up looks nice

can i ask - are the studs fitted to the hub, or to the disc, then go through the hub?

And what studs did you use?

Thanks
