Front and rear spacers with my wheels

[Caramanos2000]

I currently sit at stock height and would like to keep it this way for now. My wheels are 15x6.5 with either a 38 or 40 offset. I wanted the 10mm (could I get away with the 13mm?) penguin spacers for the rear and was wondering what kind and size (thickest without rubbing issues) of spacer I would need for the front? Also would adding some washers to the bottom mounting bolt give me some rear camber? Im only looking to get another degree or so in the rear.
