1.5 Way Diff from Powerhaus

I've been making some enquiries for a new differential for my newly acquired porsche 930 g/box & this has led me to Powerhaus in the US.
I have been in contact with Ryan Zielinski & he has reccomended their 1.5 way chromoly LSD unit. I was wondering if anyone has had experience of these units? For $1500 they seem a very good buy for the specification:

Chromoly construction 105 way LSD with 5 oversized clutch packs per side. Locks up to 100% on acceleration & up to 50% on deceleration.

If it is for a street car, it is completely wrong. Very good for a race car.
On the road the coast lockage should be double then the traction one, and a torque sensing unit is the best with the self adaptation of the locking factor to the ground friction coefficient.
