Yes, max out the neg camber of the stock suspension! It will probably be somewhere between -1.0 and -1.5. This will work better than the stock values but you'll still tear up the outer edge of the tires.

Ultimately, the alignment you choose will depend on what you aim to accomplish, the class (if any) you compete in, and what mod's you do to the suspension. Most street/track combo cars (BSX type) run -2.0 to -2.75 camber. Most Boxster Spec cars (BSR) run -3.0 deg or more camber but they are mostly trailered and not street driven.
