What does the spring rate mean?
Are my Eibach Sportline going to be any good? I was looking at the numbers and it says 2.5 for rear and 2.0 for the front. Tein and RS*R are like in the 3.0 Does that mean they are better than Eibach? The higher the number the better? I just bought the Eibach with KYB AGX. Will this be a good setup? I'm starting to worry.

Most normal factory REAR designs have a 90-120 pound per inch [1.6-2.1475 kg/mm] WHEEL rate [the springs may be stiffer than this [up to 4 times if they mount in middle of lower arm] as the angle and where the springs attach to the hub may vary creating less than 100% coupling........even 25% even 20% coupling.
Same with sway bars ......do they mount to hub, shock, or some midpoint in lower arm.....so a bar can be 100% > 20% coupled to the wheel.
Springs main purpose is to hold up and isolate the body and to drive the wheel tire back down after an upward bump.
In racing body roll is bad because it delays precision reaction to angular changes and there are no bumps so human fatigue is not the factor it might be on the street .
