I raced the SV2 for 2/3 seasons and never had any problems with the diffs, rebuilding them every 4/5 race meetings. Do you run the diff tight enough, using the locking grub screw to ensure it doesn't come loose? From memory, I used to back it off 1/8th of a turn once assembled.
Also, are you running the diff with the main diff screw on the left hand side of the car? (left hand being the non drive side)
I always found them very reliable, and only ever ran ball diffs in my KF2. In my opinion they just feel nicer to dive, and offer more consistent grip.
