Effects of Spring Selection
Makes the car more responsive.
Car reacts faster to steering inputs.
Stiff springs are suited for tight, high-traction tracks that aren’t too bumpy.
Usually when you stiffen all of the springs, you lose a small amount of
steering, and reduce chassis roll.
Makes the car feel as if it has a little more traction in low grip conditions.
Better for bumpy and very large and open tracks.
Springs that are too soft make the car feel sluggish and slow, allowing
more chassis roll.
Makes the car more stable, but with less front traction and less steering.
Car will be harder to get the car to turn.
Turning radius increases.
Car will have much less steering at corner exit.
Very stiff springs are preferred on very high-grip tracks, or if the track
itself feels tacky or sticky.
Makes the car have more steering, especially mid-corner and at corner exit.
Front springs that are too soft can make the car oversteer (lose rear grip).
Makes the car have less rear traction, but more steering mid-corner
and at corner exit. This is especially apparent in long, high-speed
Makes the car have more rear side traction mid corner, through
bumpy sections, and while accelerating (forward traction).
Softer spring are often used to increase grip; but funny enough, stiffer springs can at times can actually give better grip. You will always have to test to find the ideal set-up, the top drivers employed by manufacturers always do. Springs are quick to change so if you're not sure; test by using medium stiff springs first, and then change to hard or soft to test which works best. Only trouble with it is that damping should also be changed to suit springs.
