What is the main difference between softer and stiffer springs?? And how much is shipping to CA?
The firmer spring rate is going to have an edge in performance, the softer spring rate is going to have an edge in ride quality. Koni recommends the firmer spring rate for the VR6, 1.8t, and TDI's. They recommend the softer spring rate for the 2.0. That being said, some people do run the firmer spring rate on 2.0's, and vice versa.
