J for your car use keep it -2.6 to -2.8 front and 2.0 rear. Going over -3.0 front will kill the inside of your tires, especially Cup tires where the tread is much less vs. street tires.
RE-11 is known to wear on the outer edge when the pressure and camber are not optimal. Also why I switched to AD08 where the tread design is more "wear friendly".
In terms of pressure, Michelin has a good quick start guide in terms of how to set up the tire pressure and camber. http://www.tirerack.com/tires/tirete...nd_Feeding.pdf
Last thing to keep in mind is that the optimal set up for the race track will most likely not work for extended street driving. You can only make trade offs and find a middle point which works OK (not great) for both.
