Fresh: Camber is a basic move; something you should always do if it is adjustable.
Think of a picture you've seen of a car cornering at speed. The outside front tire is tucked under a bit, because it is taking the most load: deacceleration and turning the whole car, more or less by itself. The outside rear wheel looks the same but not as badly because all it is doing is following the front wheel.
By adding camber (technically,
negative camber - they screwed it up in the game), you are tipping the top of the tire in, so that when it is the outside wheel in a turn, it is standing more or less straight up and down. As said above, this maximizes the contact patch of the tire and keeps the load on the tread rather than rolling onto the side wall.
The downside is that when you are travelling straight, the load is biased towards the inside of the tire, which costs you some ultimate traction for braking (on the front tires) and acceleration (on the drive tires, whichever end they are). Typically 3.0-3.5 degrees of camber are what racers run (more or less if the rules allow) in front. This is a setting with a good compromise between improved cornering and reduced braking. Rear values vary, but I would start at 1.0, then adjust that up or down half a degree to balance the car for neutral handling between oversteer and understeer.
This will improve your handling but is not a magic solution by itself. If I'm modding a car, I always buy the full-race suspension and lower the ride height to about 3/4 of the way down, and stiffen the springs correspondingly, and also stiffen the damper rebound while softening the bound. The spring changes lower the center of gravity and reduce body roll, and softening the damper bound allows the car to absorb bumps more easily, while stiffening the rebound helps with weight transfer and also makes sure the tires get back into contact with the road quickly after bumps.
