RE: Camber, caster and toe for drifting
depends on the tires you are using. for toe go anywhere from 0 to 3 toe in in the rear and 1 out to 1 in in the front
camber depends on tires yokomos - 2-3 in the front, 1-2 in the rear, others 0 should work, 2 front 1 rear works well if you are constantly changing tires.
castor doesnt really matter much it will change the turn in and mid corner characteristics of the car but generally anything should work.
