I assume there are some or else KW would not have gone that route for our cars. Also, wouldn't the reason why KW has not published the spring rates is because it varies (progressive) and is not static (linear)?
On a positive note, I have now ruled out H&R...but now have added Swift into the mix.  |
I would read the following thread to learn more about swift and the benefits of linear springs, and specifically the last post which contains an email response I got from swift
Progressive springs are a bandaid fix to soften up the ride from lowering the car too much and overloading the shocks since they do not work in an efficient range when lowered too much. swift has a, still not ideal, much better solution using linear springs.
