alpha_003 I think you'll pretty much be able to do what you want to these.
The axles are very compact, meaning not much extra useless junk on them and they are wide so that helps and from what I have read bearings are a must or else you will wear out the gears some what fast.
As far as torque, in stock form I'd say they are lacking a bit.
From what I have read if you increase the torque you will have problems at the wheels with stripping out so that needs to be beefed up also.The person in the other forum drilled and pinned the wheels he used (I cant remember if he used mini-T wheels or not)
I think mini-T shocks could be used if you have a custom chassis and a slightly longer wheelbase.
