hey im about to purchase a set of tein ss im a noob so wut do the spring ratings mean? the ones im buyin are 8k and 6k i wanna ride nice and low could i do that with this set up with out bottoming out?

 

K is an abbreviation for kg/mm, which is the measure of spring rate. Multiply by ~53 to get the rate in lbs/in.
8kg/mm means that it will take 8 kilograms on the spring to compress it 1mm. Alternatively, thats something like 447lbs to compress the spring one inch. Higher rates lead to stiffer rides.
How low you can do depends on a few things, but if you don't do anythign silly like slam the car within an inch of its life (where you will see no handling gains anyhow), you should be OK.
