Ball diff is good on the twisties... but does nothing for straightline
speed. On a small tight track it might be an advantage.
(Then again, there are others who've tried either the TA02
one-way diff or they've been using epoxy as gear diff lube

..)
Drawbacks with the ball diff include
1) need to pull it out to adjust
2) sometimes the adjust screw moves by itself
3) the splines on the outdrives can strip/wearout
I have 2 cars, only one with balldiff.
There was one day that I lost a front wheel on the BD car.
Didn't realise it until half a lap later...
