info on C4 springs. Primary question is how to decipher the code on the spring to determine spring rate.

Anyone have the info??

all you need is the RPO.

Z51 - stiffest
Z52 - not as stiff
FX3 or F45 - softer yet
FE1 - soft

Bogus...thanks for the info. I can use that.

What I am really looking for is how the code on the spring equates to a spring rate in pounds.

I have an 84 front spring with the code "NYR" on it. What does the NYR mean?
