The weakest link is the T1 PCD CV bolts at the output flange. The bigger CV PCD of the Porsche and T2 reduces the shear stress on the CV bolt when loaded. The same, M8 bolts are used throught the automotive industry.

Racing axles have a lower torsional rigidity which means they can store potential energy and wind up like a spring, which reduces shock loading in some cases.

The T1 and 944 axles are indeed the same length. The T2 axle is longer? The 951 axle is longer.

The T1 and T2 axles are the same diameter. The diameter of the 944 is bigger.

The T2 and the 944 CV has the same PCD. The T1 is smaller.

The T2 CV has the same spline as the T1, only ~1-2mm longer (axle or CV centre needs trimming to fit circlip)

This will then couple a T1 axle to either a T2 or 944 hub flange. The same goes to the output flange of a Porsche trans, a T2 trans or to a T1 with T181 output flanges or a T1 with a Quaife LSD.

If and it's a big if, if the T2 axle was the same length, as a 951, I'd have my polished 951 arms on, even with only the T1 diameter axles, 'til I can get the Quaife and use the 951 axles.

'hope that helps,
