spring rates, which is good for sport use? Options

[tufy]

before i ask my question i want to explain what spiring rate is..
Spring Rate is the amount of weight needed to compress a spring a certain . Springs are rated in LB/in (in metric system kg/mm), or specifically, how many pounds of weight are required to depress the spring by one inch.
Springs that have a low Spring Rate are soft, while springs that have a high Spring Rate are stiffer.
Question is, what spring rates does every one with coilover kit have. and are you happy? what is optimum spring rate for sport use. 10 kg/mm front and 8 kg/mm rear seem ok to me. wht do you think guys.?

mine are 7 kg/mm front and 5 kg/mm rear these rates suffice for spirited driving on the street. but i would prefer a lil bit harder for the track.

for example:

trd made their coilover specs for fwd
8-F
6-R

Since your car is awd i believe you would have to look at the spring rates of kits made for awd applications. Some rates are the same and some rates are different when comparing front and rear.
