can someone give me an explanation about spring rates? what is the difference between 350 lb springs and 450 lb springs.

 

Spring rate refers to the amount of force (measured as lbs.) it would take to compress (squeeze) the spring 1 inch.

so the higher the number the stiffer the spring?

 

and what is a decent spring rate for my 93 Si?
I'm interested in setting up the car for autocross as well as a daily driver

 

my friend who drag raced had a nice set up

650lbs in teh front 1000 in the rear... boy that was a fun car to ride in

 

I am currently getting ready to drop in my JDM H22 with LSD, Spoon ECU, and RSR Header and recently purchased some coilovers. I am using Skunk2 coilovers and I have spring rates of 700 in front and back. Lemme tell ya, its pretty stiff. Ok, ok its stiff as **** but it gets the job done and it'll be really good when my motor is in. I recommend a spring rate of 500 for road coursing and daily driving.
