Most of the spring rates on coil overs increase as they compress. Making the spring rate feel higher than rated. There are very few brands I would trust their spring rates to stay linear.
Swift springs are a common upgrade in Japan because of their linearity. There are many more brands made in the US or available in the US. Going to a more linear spring at the same rate will improve the handling.
Hypercoils, Eibach and Swift are the only ones that usually fit.
