Let's talk high performance CVs/Axles, What are today's options Options

[vintage914racer]

I became the member of the failed CV joint club when the inner joint on my 914-6 vintage racer exploded entering turn-one at Road America. Just to spice things up, the tranny I was running has a welded diff, so the failure sent me into a spin....fortunately I avoided contact damage.

My winter project is to upgrade to a guard LSD and find beefier CVs that can handle the power my car is putting out.

I know there are options out there that consist of taking other Porsche CVs and adapting for use. I'm hoping to find an off the shelf option, as my available time to tinker in the garage is limited these days. I see Tarett sells high performance half shafts and I know Renegade does or did at one time.

Is there anything else out there that I should know about?

I'm running a 108mm setup also:

* 1970 - 1973 sportomatic trans flanges. Part number 901-332-209-15. I believe 901-332-209-22 works too. These are coarse - splined and IIRC about 3/8 longer than the manual transmission flanges, making up part of the difference in length between 914 and 911 axles.

* 1969 - 1975 911 CV / axle; P/N - 911-332-033-08; 108mm 4 bolt CVs.

* early 911 stub axle / wheel hub - sorry I don't have the exact years handy.

Saw this combination described on the old listserv many years back posted by someone who raced. Has been working fine with my 3.2 for a few years now.
