Or, you can just use real 914-6 hubs/stubs for your conversion.

I ordered in some Box outer hubs.
(IMG:http://www.914world.com/bbs2/uploads_offsite/i916.photobucket.com-8123-1422991605.1.jpg)

If I read this post right. I need a 911 axle/stub, drill and tap for a rotor mount and a spacer .?

With my build being a Subaru motor and trans , what outer CV will be needed ? Being new to this it looks like a 911? Is it the same as the 944 CV ?

My plan is to use the axles from ColdWater914. Subaru on the trans and it looks like 914 or 944 on the axle.

With this in mind ,if I go with a 911 rear vented rotor with 911 parking brake and kit. What will this change ? What will I also need ?

Here is a little add to using the Boxster hub. I made a small cut on the stubs to make resesed in the 108mm hub. Don't forget the radius when cutting the stub . And to reuse the nut and the holes in the stub I made a washer/spacer.

^Looks good, instead of cutting the stub axle I would have just added a chamfer or radius or counterbore to the spacer.

Make sure your spacer is as hard as your nut (HRC) or you will have gaulling on your bearing surface and end up with a lot les clamp load in your joint.

Thanks David,I will keep a eye on that.

So it will not be plug and play. The the hub will need to be cut to clear the bearing flange. If you look at the green paint ,its missing.

Going to be tight in their with the 108's !

And I stopped at Patrick Racing and got the trailing arm stiffeners. Welding in the AM.

(IMG:http://www.914world.com/bbs2/uploads_offsite/i257.photobucket.com-8123-1423621003.6.jpg)

One last thing,I don't think it will need any cutting on the stub shaft. More in the AM. But I have a set ! (IMG:style_emoticons/default/chair.gif)

Any chance the Boxster bearing flange will bolt to the 914 trailing arm.

Good idea. I will look at it tomorrow. But I don't think so. It is a non-symmetrical pattern on the Boxster.

If I built a holder I could cut down the bearing flange shoulder ? Maybe in the field it could just be ground down ?

I will cut one of the stubs and see what clearance will be needed. Need to take a look at the 130x4 hub. (IMG:style_emoticons/default/beerchug.gif)

Huston we have launch ! It will work,but it takes some modification. The big problem will be the bearing retainer. The in side lip will need to be cut down. I used my mill but it could be done with a die grinder. Next will be the cut on the hub. At this time I do not think a cut on the stub will be necessary. (I cut both of mine but a step in the new spacer could take care of that.

With a Boxster hub and a 911 28 spline 108mm stub you can have 5x130. (IMG:style_emoticons/default/cheer.gif) But you will need access to a lath,mill,some steel and time. (IMG:style_emoticons/default/beerchug.gif)

Because I will be using a Subaru trans I can't help with the link between the 108mm flange and the trans flange ? Sorry, I'm sure someone here can help with that. Their maybe other ways but this is the way I went.

Order 4 911 rear bearing covers so they are doubled up ( 2 stacked) on each side. It will give you an extra 1/2 inch space over the 914 bearing retainer between the hub.
The run $9-10 bucks a piece.

Here is what I found.

The 911 flange is .090 thick with a .213 flange. To thin and to tall for the cut Box hub. This was used as a backup to the parking brake hat. (note this hub could not be used if you were going to use a 911 parking brake system)

Box retainer is .212 . To thick for the cut Box hub.

914 is .115 thick and has a cut flange of .210 ( this is the inside flange ) clears the cut Box hub by .030+-. And it has the outside flange witch is a big plus.

I still feel this is the best IMO.

Did you measure the wheel mating surface compared to the original one?

Meaning will the wheel be in the same place or stick out further or less relative to the fender or inside trunk wall? I guess the track would be the correct term?

The way I looked at it, the brake caliper is in the same position (no spacers stock mount) and its the 914-4 rotor. This should make every thing the same. IMO
Right ? (IMG:style_emoticons/default/idea.gif)

Might this be an option for the flange hitting the hub?

These are lighter and flat.

Yes this will work but may need to be chamfered ?

I got in touch with Chris Foley today and the diameter of the hole in his bearing retainer is 2.75". I measured the boxter retainer and it is 2.71. Thickness of the boxter plate is 0.196", CFR's is a bit thinner. There should be no reason it will not work so I just ordered a pair. I think that the issue with the 914 retainer is the smaller diameter opening combined with the raised lip.
