The center diff doesn't load or unload to the front or rear quicker normally it will simply unload quicker where the most force is... to have a constant well controlled brake you don't want it to unload quickly imo as you may depending on your position or how many tires are grounded get drastically different braking results. I think the diff weight in the front or rear will determine more on how quickly they unload in comparison to each other than the center diff itself causing your front to rear issue (front braking harder). If you have a huge difference and not typical setups like a front at 10k and rear at 2k or somthing very drastic, your results will be different too and you may need to go lighter to compensate. Obviously each truck and setup can react differently, but generally speaking of course about typical setups this is what I got for results. Again as I stated before the 500k is standard in the traxxas setups but they have a transmission as well changing things a bit.. typical 1:8 are direct drive off the center diff, also keep in mind the revo spec diffs are up to 30-60k range on the front and 10-30k on the rear as a minimum. I race a erevo and run 60/30 and it is perfect after many trials. 8ight as listed above I use 7k 10k 3k I think it was.. I think thats right..

who knows.. maybe I had untypical results.. as I have not done a ton of playing with motor brakes on a center diff as such is this setup... the owner has spoken and I would go w/ him ;P

The brakes are fine at nearly all weights IMO, the accelleration is where its bad if too light. I am basing alot of this on my custom erevo, and it had to have no less than 500K.

I'd bet you didn't try brakes at 10k or less wt though:P Agreed with the acelleration if you are getting near 50+mph. It's not as bad though at 45 or less which you typically are even on the straight aways on most tracks with the 1:8 scale center diff driven buggies and truggies. The (e)revo center diff is a different story of course.
