TBH I spent considerable time with the ball diff including making a sanding tool on my lathe to hold the plates making sanding much easier and more precise but I found the slipping a real problem when used with 16 or 8 balls, fluid filled, unless you overtighten. Its not that obvious at first that its slipping. Don't get me wrong, car feels good, reactive, great rotation but as soon as you get to a big outdoor track there is a clear lack of forward bite in comparison to the gear diff.
Overall, I was quicker with the gear diff everywhere under all conditions, I really like the balance for my driving style with 2000 CST
