real fast suspension question
 

hey just curious what exactly does this spring rate equate to in number

8.400 front ND 180.64.61 rear.. they are ground c's and another question .. havnt installed yet jus got um with the koni yel's but shouldn't it have a little key like the others to lower them... before i call and ask for one
thanks

The 180 is the length, the 64 is the diameter, and 61 is the spring rate in metric units. The spring rate is in kg/cm units, so you will need to convert it to lb/in to find the standard measurement.

You don't need an adjustment wrench either. Just loosen the allen screw and turn by hand.

so what would the front bee...
