Are you planning on changing your springs? Going with a stiffer, and slightly lower spring will help you gain some negative camber...
Also, I might suggest getting some Camber plates, as opposed to Camber bolts. If you're going to be doing racing, a camber plate is a much more heavy duty mount, which allows for much more adjustment.
Remember, its not just about adjusting camber, but also maintaining camber... you may adjust camber to one setting, but in extreme cornering / braking (auto crossing) the alignment settings can change several degrees!!! Especially when using the stock rubber strut mounts.
Check out our Caster / Camber plate section...
