Additional negative camber will increase front end cornering grip, but it will also increase tire wear at the inside of the tread, decrease straight-line grip when braking or accelerating, and decrease straight-line tracking ability. The stock camber spec for a BJ Proteg is 0.5- 1.0 negative. 1.5-2.0 of negative camber will provide good handling without extreme tire wear. Hardcore autocrossers and track racers may require 2.5-4.0 of negative camber for maximum front end grip, but this much camber will generally cause excessive tire wear and front-end wander on the street.
