I'm running a Faktor in Predator Heavy on a 1/5 mile track with the following setup...
LF - camber +.25° caster 6°
RF - camber -2.75° caster 10°
Weight
Front 44%
Rear 56%
Left 62.5%
Cross 68.5%
I think the baseline calls for less cross and rear weight but this is what has worked best for me so far. I don't know how well that will translate to a lighter driver but maybe it will help you a little.
