Unfortunately, original recommendations are written for bias-ply or cross-ply tires and sort of oversafe setup. IMHO they are pretty useless with your combo. If tire costs are important, it's camber and toe that tear tires. Caster doesn't have much effect. How about zero camber or maybe -1/4, caster +1, toe-in 1/8, maybe 1/16. That isn't too harsh on tires, but would allow you to enjoy more spirited cornering than stock setup.
