To upgrade to the BP diffs, all you need are part #102692; it is just swapping the ring and bevel gears, all the internals are the same.

I've been running 20k/10k. Here's some info on what increasing/decreasing the thickness of oil will do:

Front

Thinner
• Increases steering into corners (off-power)
• If oil is too thin the steering may become inconsistent,
especially it can lose forward traction (and steering)
during acceleration out of corners

Thicker
• Increases stability into corners during braking
• Increases steering on-power at corner exit

Rear

Thinner
• Increases cornering traction
• Increases steering into corner

Thicker
• Decreases rear traction while cornering
• Reduces wheelspin

Most truggies run between 7k and 15k in front, and 1k and 10k in rear from what I've found (results may vary). I run 10k/30k/3k in my RC8Te, so I basically took roughly the same ratio and went up in thickness due to the weight of the vehicle, although I may reduce it to 15k/7k.

The tranny should be fine under 6S power; there are some benefits to going to a center diff, but it is also not a straight forward mod either [either you end up running really large spur and small pinion, or you need to do a gear reduction of some sort].

Jahay, I know about the Savage Suspension conversion kit; pricey and undoubtable decent, but try finding individual parts for it *if* something does break is nigh impossible (try it for yourself; go to amain, tower, stormer, horizon, etc. and see what you find... not the entire kit but just say a rear hub) so that makes it much less of a quality upgrade.
