This car uses a gear diff, not a ball diff. With a ball diff, you can tighten it by simply tightening the bolt that goes through the center. With a gear diff, the only way to tighten it would be to put heavier diff oil in.

Try using a heavier diff oil. The kit comes with 10000wt diff oil and with the more powerful .12 engines on the market, that is too lite. I use 30000wt oil in my rear diff and it helped tremendously.

Make sure that the four o-rings and washers on/in the four small spider gears are in tacked. Also check the o-ring and washers for the out drives are good.
If your running on a track 30,000 is the starting point. If your running a un-prepared parking lot you might need something softer?
