RE: Going from 4wd to 2wd advices needed
Personally, I'd set it up to run way more camber in the front than the rear (I'd suggest something like 1-2 degrees rear)
If you have too much in the rear you'll just wear the tires out on the inside edges.
On the front I'd plan on cranking in more camber, at the track, if you're looking for even more steering. Oftentimes I use up to 4 degrees indoors.
A touch of toe-out is good, it makes the car track straighter on the straightaways.
