Looking at 6-700hp and a lot of cruising, minimal Auto X, road racing. I know I should have went S trac and 35 spline but I already have the axles and I don't plan on doing any 5k 1/4 mile launches on stickys. Im running this until I kill it.

If you are referring to the Strange nodular case as the nodular S case, it will do the job quite well. It is a great balance of light & strong. We raced them for years with no failures or problems.

31 spline axles will be fine, if you have a good brand. Your weakest link will be the Tru-Trac.

The aluminum "Daytona" pinion support is a good choice with larger pinion bearings which are needed IMHO. The only challenge here is many of the aftermarket aluminum Daytona pinion supports don't offer enough press fit for the front seal & they occasionally push out. Peening 3-4 spots around the outside of the seal helps. If you still have seal issues, let me know & I'll hook you up with a bolt-on seal retainer bracket.

Best wishes.
