I've been playing around with the Smart Diff in my E-8ight. I bought the center version because that's what the Losi pros recommend to start with. With it I noticed an improvement in both acceleration and on power turning in loose conditions. The car tracks better in the turns and the rear no longer trys to swing around. This would work very well on most larger 1/8 style tracks.

For where I drive at this time of year the SD in the center was not completely what I was looking for, so I swaped it into the front. You have to change the outdrives and spur gear to do this. The areas I drive at this time of the year are a good sized backyard track and a nice clay indoor track. Both are set up with tight turns for 1/10 vehicles. With the SD in the front the 8ight turns like mad, and pulls the front end through turns on power better than in the center. The rear of the car is a bit loose, but this helps to swing it through the tight turns. And, one other bonus is the car is incredible through the whoops at are backyard track. The front pulls so hard that it will just skim across them. In the stock setup I had to go much slower.

As for braking the SD brakes just like a regular diff, but the brakes do seem a bit stronger.
