Confused on how coilovers work...

I am kinda confused on how coilovers work. If the coils have a very stiff spring rate but has dampening adjustment, will it be a stiff ride even if I set it to a softer level or vice versa? For example, the Stance GR+ have a 725lb/615lb spring rate. Will it be a harsh ride no matter what? Or does simply having a stiffer spring rate mean that the car CAN have a soft ride, but still be stiff.

spring rates have a lot to do with the stiffness I believe.

dampening can only do so much.

Bump. Good question. I'd like to know too.

The damping adjustment will affect the ride quality and handling characteristics, in unison with the springs.

You can still have stiff spring rates and have the ride be fairly comfortable if the shocks are valved correctly.

true. just remember that spring rate is still spring rate. As long as the valving on the shock is proper to the spring rate, it can ride ok if everything is adjusted properly. But if you're running super high spring rate, then still expect a firm ride.

Yup, I would never expect high spring rates to ride like OEM, but it won't necessarily be bone shattering or anything like that in a street car.

Also, spring manufacturer and quality will play a part in the ride quality. Eibach, Hypercoil, and Swift all make some of the best springs on the market that are truly linear. A lot of coilovers use springs that aren't always consistent and that can translate into a rougher ride at times.

Coilovers can give you a streetable ride quality if you dial in the dampening correctly. What coilovers were you thinking about going with?

hmmmm, according to

http://www.rqriley.com/suspensn.htm (the ride comfort section)

The static deflection rate of the suspension determines its natural frequency. Static deflection is the rate at which the suspension compresses in response to weight. Other factors, such as the effects of damping (shocks) and system friction, alter the natural frequency of the suspension system. However, the primary determinate is the undamped static deflection rate. If this rate is used in calculations, results will likely be very close to the actual value needed for a smooth ride.
looks like springs would affect ride quality more than shocks then?
