This is not my diff... my mate Robert from Frankfurt has disassembled his diff. He bought it from you. He complained about his diff is not locking at all.

The problem is that it seems one side of diff did not work at all. It was skewed.

I use the same diff (M5 E39), but I assembled it by myself with RacingDiffs 4x clutches kit and 45x45 ramps. Now it works good. But I think I would go with 6x clutch packs, need to machining 5mm from core...
