The cars weight is allowed to roll and put pressure on the outside tyres more.
However leaning over your shock too far would make the the shocks sluggish to react into chicanes where you want the car to roll from side to side quickly.
As always it's a trade off.
Best thing to do on your car is to try both extremes on a track that has both fast & slow bends and also a chicane.
Get to know how the car feels at both extremes, don't forget to re-set your ride height each time.
This is true. Keep in mind that you can get rid of the "lazy" feeling by using thinner shock oil and/or more piston holes to increase dampening speed when the shocks are layed down more.
This type of setup is generally not good for bumpy surfaces. However, I've found that using stiffer springs that are more layed down can get rid of traction rolling without having to soften the springs up and loose corner speed. The stiff progressive rate spring setup will let the shocks soak up initial steering inputs that can cause traction rolling, but the springs will tighten up nicely and keep the car from rolling too much and losing corner speed, especially in fast sweeping corners. This is assuming that you have already tried to get rid of traction rolling by using minimum ride height, a low center of gravity (and truing tires to a smaller diameter if you're running foams).
