Transaxel, trailing arms, and axel compatability
 

So, I have a 1979 SC and I'm looking for upgrade and compatibility answers. My issue with the SC aluminum trailing arms is they don't have the bearing load capability as a turbo TA with the double bearings. Is there a difference between the SC TAs and the Carrera TAs? Can Carrera TAs take the torque the Turbo TAs take?

Can I use carrera axels with the CV joints with a 915 trans and the SC trailing arms?

I want a G50, but Im' wondering if I have to get new axels and new trailing arms as well.

Sorry for all the questions.

-P

Based on the parts catalog the SC and early Carrera's have the same TA.

That's what I thought, but someone told me the carrera arms have bigger bearings or can take more of a load. I was skeptical.

Is it possible to use the axels from a carrera with an SC trailing arm?

SC & Carrera's use the same bearing and handle the same loads.

You can use the stronger CV's and axles from the '85 Carrera.

930 arms simply permit bigger tires and wheels without compromising bearing life.

In case anyone else uses this thread as a reference it should be stated that Turbo arms do not fit standard 911s because the Turbo and Turbo-look use different pivot points on the torsion tube and so are of a different geometry. You can adapt the revised suspension pivots and then use the arms, but they do not bolt on.
