I have been trying to find the spring rates for front and rear springs (mainly for fronts but both would be nice) for my 98 XJR. The springs have YELLOW paint on them, which I believe signifies comfort springs. Does anyone know the spring rate, whether in kg/mm or in/lb ?

 

I don't have the answer yet, but I'm hoping to replace my stock springs with replacement Mina lowering springs. I'll try to get measurements of everything I can.
