Mini t dirt oval setup questions

[vwjuice]

Hi everyone, I have never ran on a oval course before. I am setting my mini-t up to race for this weekend and I am asking for questions about setups.

I have a mini t with a 7800kv brushless setup in it. I was wondering what pinions I should get for a good assortment. I have no idea what pinions to use with brushless motors.
Also I am wondering what to do as far as tires, camber, toe, etc. etc. I am just looking for help to get in the ballpark so I can fine tune it. I know the track is dirt with loose dust on top of hard packed dirt.
Any help would be greatly appreciated. Thanks
