I'm doing the 'ol up grade to a 1275 in the BI and got to wondering about
the rear end. I'm not sure if the PO just put wire wheel half shafts into a
disc wheel assembly or not and many folks have been kind enough to send me
measurements to identify the assembly. Unfortunately, all the measurements
have
been different. It is my understanding that the wire wheel shafts are
shorter and therefore do not fully engage the differential. So far,so good
with
the 948 but I am wondering about the massive power of the 1275. What have
folks
been doing? Some have suggested pressing out the shaft from the splined
knockoff , making it all longer. Does it really make that much of a
difference? Do the shafts actually touch each other inside the diff? Is there
a bolt on
splined hub which instantly converts a solid wheel one to a wire wheel one?
I've seen stronger axle shafts advertised but only for solid wheel ones. One
chap I spoke with in the UK said there were really only very few (1700 or so)
true wire wheel cars with the 1/4 elliptic axle. Any thoughts out there?
