Basic Understeer/Oversteer Questions?

Now for basic knowledge, I wanted to create a quick reference guide as to each change in a car and what effect it will have on steering feel.

For some reason I always seem to get confused on these basic changes. So if someone can answer whether doing the listed thing will increase oversteer or understeer to each one, it will be a helpful user guide for me.

Thanks

1.) Adding air to front tires
2.) Adding air to rear tires
3.) Thicker rear sway
4.) Thicker front sway
5.) Increasing rebound rate of coilovers in front
6.) Increasing rebound rate of coilovers in rear
7.) Standard staggered tire setup


If anyone has anymore things that will change the steering dynamics I'd appreciate you adding them.

Thanks
