"Think about this; when you hit a bump on the road using stiff springs, your entire car gets bounced up in the air not just the suspension taking the bump."

"The shocks are the most important part of how the car reacts with the ground. If the springs are too stiff the car wants to bounce and ride stiff"

Go down to the chart where it says "Matrix of Suspension Components and their Effects" - "Springs - Too stiff won't allow the tire to comply to the road. The car will bounce off of bumps losing traction."
