You car came with a Performance Supplement booklet that has a GM recommended "Track" alignment, along with suggested cold and hot tire pressures. I suggest you start there, as it's a solid baseline. You don't need the Moreno plates to achieve it either.
A little slice of advice; no amount of camber will provide flat tire wear on the stock FE4 suspension, as the dynamic camber loss and camber curve is non-conducive to good tire wear. Once you get acclimated to the car and reach its maximum pace, roughly -2.6 to -2.8 deg front will be about right to wear both the inboard and outboard shoulders simultaneously. If you're not routinely in HPDE advanced group or better, then you won't need that much camber to reach balanced tire wear. This is why I said earlier the best alignment is one that *you* find wears the tires as evenly as possible.
