Well, I have the same problem, just lossen your slipper clutch a little bit, that will help alot with putting power to the ground. I also have a heavier car. The tow-in on the rear helps stabalize it at higherspeeds, but I dont know about on the lowend. The camber, get some adustable tie rods, you can then adust the camber so you have more rubber contact on the road, but you'll eat your rims alive with no camber on the wheels.
