RE: Dif oil
It doesn't only depend on your driving style to get your diffs setup so you feel comfortable but different diff settings will be nessisary for different buggies to get close to the effect on another buggy. On my MP777 I'm running 5000 front - 7000 center - and 3000 rear. There are a few people on this posts who are running 10-10-1. Just experiment and make changes one at a time and you'll find what your looking for sooner or later.
