The thicker 30-spline shaft is stronger, but requires a swap of both trans and rear to utilize it. The 9310 27-spline is a nice step up over stock and allows retention of all other stock components.
The TR-6060 units have a thicker output shaft, but not compatible with T56 components.

I had RPM transmissions put the 30 spline in my MN12 Trans...had their Level 5 upgrade too....they had to machine my pinion gear to accept the 30 spline and used the 3 rip z06 case still with the RPM stage 3 390 upgrade

Old thread, but just wanted to add my experience for anybody searching this in the future.
Just broke a 9130 G-Force 27 spline main shaft in my car. Never had a drag radial or slick on the car, never been to a drag strip and I never wheel hop it. Just drive it on the street and autocross it. 767rwhp with a Dyad twin disk. Had Michelin Pilot Sports on the car for most of the 2 years the shaft was in the car. Currently have a Toyo R888 on it.

The 27 spline aftermarket mainshaft is a stout piece. I've actually never had one break after being installed.
