I’ve used diffsonline for all of my LSDs (no issues but driftflo has more clutch-type options) but I’d probably go with driftflo if I was starting over. Far better than a SC and it keeps the characteristics of a NA 4.0 L V8. I’d recommend a stage II tune with a raised 8600 rpm redline and DCT software that updates the FD ratio.
I’d strongly recommend a halo seat if you’re going the full cage route. Hans + halo provides the most safety for your head and neck coming from someone who’s had 10 spine surgeries!

Why driftflo over diffsonline?
