A spring rate like, say, 250 lb/in, means that it will take 250 pounds of force to compress the spring by one inch. Spring rates for a lot of JDM brands are listed in Kg/Mm, which measures the same thing, just in metric units (Kg's of force to compress the spring 1 mm).

Remember, stiffer does not always equal faster, or better handling. Also, choosing the right spring rates depends on a lot of things. You should ask yourself the following questions: Will I drive this car every day? Do I want the car to over or understeer (if you're lucky you can balance out the suspension completely, but this can take a lot of trial and error. Also, what other suspension modifications have been done (sway bars, etc.)

+1 BeQuiet,......................stiffer not always faster.

Springs that are too stiff cause loss of grip in the turns due to
the car bouncing around. Unless you are on a smooth road course.
Too-hard springs beat up the suspension,
and beat up the car, as well as tire a person out.

I prefer spring rates close to stock, since that is what the car was designed to use, and my experiences have shown me that I can make a car stick to the road in a turn with modified coils from stock springs ..............something I have demonstrated to the people who have ridden with me..................and something the critics/haters choose to ignore. :)

BTW, I spend only minutes hauling groceries, so my car is set up for
the hours NOT hauling groceries.-Bob

As to phones, I am doing on the road repairs on some days and can't answer. People sometimes leave a message and their phone number gets garbled.

My apologies. Would you send me a copy of the missing
email?-Thanks.-Bob

If this is going to be just a street car just go with a progressive spring rate which doesn't have a measure I don't think..

You can tell what a progressive spring looks like cause on the ends the coils are closer together..

Since you have a drifting car (well you have a s14) I think for drifting you would wnat to run soft in the front and stiff strings in the rear.
