hi rob max camber wil be governed by tyre wear so try to build in a window of adjustment for later when you get on the road, max caster is up to you just be aware that the more caster you have the heavier the steering will be and you will have a jacking effect on the inside tyres in turns (this is good for race cars with locked diffs but not for road cars) pic is of my front caster rods with adjustment for anti dive and caster i have 16 x 8s with 205 35s on the front of my ute and have about 50mm clearence to the foot well at full lock , it all depends on the combination of all your front end components
