Too long winded.
Basically:
stiffer front springs increases understeer
stiffer rear springs increase oversteer
more toe-in increases understeer on that end of the vehicle
more toe-out increases oversteer on that end of the vehicle..
stiffer antisway bar front increases understeer
stiffer antisway bar rear increases oversteer.
antisway bars can make your car slower. They are best used only to
balance front and rear suspension cornering.
Lowering a car will not necessarily make it quicker, especially if its >0.1"
Flatter cornering is not necessarily faster; it is only if the inside
tire stays on the ground longer. 2 tires are better than 1.
wider, shorter tires are not necessarily faster.
spacers in springs stiffen the spring.
spacers on hubs increase camber on independent suspensions
increasing camber will not necessarily help cornering. about 1 degree is generally max static.
increasing caster (lean back) will generally assist cornering but not if you do too much. Stock vehicles generally run around 2 degrees; a maximum of 6 degrees is extremme and mainly for non-twisty tracks.
increasing tire pressure is same as stiffening springs
stiffer shocks are similar to stiffer springs. actually they just control stiffer springs. Failure to
match springs and shocks are a major error.

Now you know why chassis engineers have such a hard life even with computers.
