what is the differences between the koni yellow, blue and red??

 

ones yellow, blue and red

 

yellow : adjustable while still in on the car, valved for higher spring rates, koni says up to 600 i think?

red: adjustable, but you need to remove and put the rod in a vice, compress shock, then rotate to change setting, not valved for as high a spring rate as yellow i think

blue: didnt know there was one, i know makes a ready made race shock but i thought they were yellow too, my guess is just much higher valving than other yellow

 

There are no Koni blues. The only blue shocks I have seen are Tokico HP's.
