Springs

Springs

When a tire hits a bump, it’s pushed up and than back down. Springs can sustain the bumps and keep the tire pressed agains the road so that you maintain grip over bumps. This means that a soft spring is going to give better grip and a more comfortable ride on a bumpy road. But, on a smooth racetrack, stiff springs are usually going to do a better job. Why? Because springs do another job, which is to support the movement of the car’s body. When you brake, the car’s body nosedives. When you turn, it leans sideways on the outside wheels. When the body of the car moves around, it moves the tires to an angle so that they are no longer facing up and-down relative to the road.

Stiffer springs are going to produce a more harsh ride over bumps, but will make the body of the car more stable and less twitchy when you brake, accelerate and turn and, since the track surface is generally smooth, you can stiffen the springs quite a lot. Of course, there’s always too stiff, where the car bounces over bumps, even the little bumps of the racetrack. Stiffer springs make the car twitch less, but more quickly, so the car responds to inputs of steering, brakes and accelerator faster. This gives you more grip, but a sharper transition into a skid and with less warning.
