Not only does the camber dial out any understeer it also promotes better tire wear particularly in the front.
I played with R888 tire pressures yesterday at Pacific Raceways and found the optimum HOT presures to be 44 front and 42 rear. That equates to around 34 front and 32 rear COLD.
If you're looking for TOYO tires try Tires Direct http://www.tiresdirect.net/index.cfm prior to the end of June for some great pricing. My 245/40-18 and 255/35-18 combo can be had for $820 including shipping to Seattle.
