* if you use SC or any later 5 lug hub centric hub, you need a 5mm spacer in between the hub and the bearing. Early, lug centric hubs do not require a spacer.

Oh, I got it : you meant on the outside, before inserting the SC wheel hub ?
This will put the rotor in it's right position ?

between the hub and the bearing. Hub centric hubs are 5mm wider where the bearing sits.

I'm sorry but I don't get it. What part are you calling "hub centric hubs" ?

It looks like swayaway is un reachable...

But this website seems to sell the correct axles :

The hubcentric hubs have a raised area on the hub face that fits inside the wheel itself, virtually locking the wheel to the hub rather than relying on the wheel studs to keep the wheel centered. They're wider where the bearing sits so it needs a 5mm spacer to keep the bearing within the correct placement in the trailing arm. I'm in the middle of this operation now so i snapped some pics for you.Attached Image Attached ImageAttached Image

Thanks, that's much clearer now.

That's the wheel hubs I'm about to purchase, from a 69-73 car I believe.
I guess they'll not need the spacer (the raised part on axle side looks higher than yours).

(IMG:http://www.914world.com/bbs2/uploads_offsite/i.ibb.co-21433-1596572758.1.jpg)

The SC parts I might use are the 100mm stub-axles.

These are the remainings of the old bearing, you have to remove anyway before you can install the hubs.

Of course, but I was referring to the raised part underneath the inner bearing part.

I gathered all parts for my conversion and will have the 914 axles machined very soon.

One last question : which brake rotors shall I order ?
It looks like the 914/6 rotors are 1mm thicker and 4mm wider in diameter, so shall I have 914/4 disks drilled to 5 holes ?

In both cases, I assume the wheel hubs pictured above will stay at the same depth compared to the trailing arm and caliper. Am I correct here ?

Your rear hubs are 911SC 1974-up. You will need 5 mm spacer on hub before installing hub in to axle bearing. Use the 914-6 rotor and have it machined. It is a direct bolt on. -4 rotor hub screws DO NOT line up.

Yes, that was the plan.

machined to take what out ? 1mm thick out ?

You mean line up with calipers ?

Both disks have the same height though : 79.5mm

The -4 rotor screw holes that hold rotor to the hub are not the same. -6 rotor is a drop on fit. Put the -6 rotor on the hub and see what the how it fits. Some people have reported that no machining was required. You can sand 2 mm off each pad for the thickness of the rotor, that way you may only have to take 1 mm off the diameter. You might be able to use a die grinder and take 1 mm off slot on calipers. If that works, no machining of rotor is required.

When I went 5 lug, I used early 911 hubs, 911T non vented rotors and 914-4 rear calipers. I had to reduce the outer diameter of the 911 rotors by 2mm. That cost me $20 at my local mechanic. Everything else bolted on. Brake pads worked fine as stock.

Machining 914-4 rotors to 5 lug at a machine shop would have cost more.

I get it, thanks guys !

I'll wait for the parts and try them in real.
My machine shop asked 40euros to machine the 914 rear axles (to fit the 944 CV), so I guess a diameter reduction wont cost too much.

What if you could get a 5-lug rear hub that's a direct bolt-on, and uses 914-4 stock axles?

Announcement for part number 914 331 605 5 LUG coming soon!

wonderful but you would still have to have a stock 914/4 rotor drilled to 5 lug....

@UROpartsman will you be making new 914 CVs at some point?
