what are the differences between different length springs in a coilover setup?

[fo0manchu]

I have the the coilover sleeves and springs that you can add on to any strut housing to make them them into an adjustable coilover setup. I was just wondering if the length of the spring made any difference on performance or feel of the ride. Assuming that both springs are the same rate. For instance, is there any difference between a 10" spring and a 8" at 200lb each? Does one perform better than the other? thanks

damper travel... if they dont' say groudn control, you can throw them away.

Just an FYI, usually coilover springs are longer/shorter and have thicker/thinner coils to raise/lower spring rates.
