Exactly what I was looking for, thank you.

 

i'm sorry buh when it comes to spring rates what exactly does that mean?...sorry

 

Whats the stock rate?

 

That was my next question Deus. I even asked The local Nissan dealership and of course they are clueless.

 

As far I know nobody knows. Maybe Progress does, if they tested the stockers before they made their lowering springs. They had to have some sort of baseline to work from, especially since IIRC their springs are said to be 20-30% stiffer.

 

IIRC, Pounds of pressure per square inch to compress the spring 1 inch.

 

According to Progress Auto

Our records show that the stock spring rates were 160 pounds in the
front and 278 pounds in the rear. Let me know if you have any other
questions.
