The rear is now done, now on to all the things that I've been avoiding.

Are those parts powder or Cerakoted? They look fantastic.

Great pictures!

The spring plates are Cerakote, the torsion tube is Steel-it and the torsion carriers are VHT caliper paint (if I recall) baked on the BBQ lol.

Wow! Looks AMAZING.
May I ask what diameter torsion bar you went with? I believe that OEM was 15 or 16mm. Not sure if M030 was thicker.

Thank you!

Do you mean torsion bar? The stock 968 bar is 25.5mm (and I think the M030 is the same) which is what I'm putting back in. I'm also going to be running KW coilers so I don't think I need to upgrade the bars really.

If you meant sway bar then I'm putting in the 19mm M030 rear bar.

Yes, I meant torsion bar and 25.5mm had escaped me. Thanks for clarifying.
Looks great! I'm sure the rest of your restoration will be as clean and well done.
You doing anything to the torque tube?

Well I'm doing a 6spd swap and had managed to get a hold of a non-split torque tube. I've cleaned it up and painted etc. And was going to leave it at that, but now the stupid voice in the back of my head is telling me that I've gone this far and should just man up and install the Super Bearings. So I will probably end up doing that too.

awesome and patient work done - great pics too (good to see separated refurbished parts in detail - gives more information and visual context). Keep it coming..

If you're that far in, I agree that you should put in the new TT bearings. It's not the cheapest thing to do but it can be done at home: https://benno928.wordpress.com/2022/...e-torque-tube/

New to the 968 world. What's the deal with split torque tubes? Frequent occurrence? How?

Funwithdesign

Not so much an occurrence as a factory feature. During the early years of the 968, Porsche used a torque tube with a lateral slit that runs maybe a quarter of the tube from the front, I think it was intended to reduce vibrations. However the slit ends up deforming the tube over time with age and water etc etc. This then leads to issues with the bearings and also makes rebuilding the tube a bit of a crap shoot. Some folks have creatively welded the front of a 944 non split tube onto a 968 split tube but it requires some jigs and welding skill.

For some reason the tiptronic tubes were still split well into 1994 (probably because it wasn't worth it to change for the low production numbers).

Anyway, the non split ones are rarer and more desirable for obvious reasons.

Interesting. Thanks for the detailed explanation. Dug around and found this post which helped me understand this a bit more.
