Hey guys,
I am thinking about getting some koni yellows or kyb agx’s and i’m not sure what kind of spring to get. I want something that doesn’t lower car much and that can be taken to the track yet drive on the street. I’m not too knowledgeable about spring rates and would like to know if anyone can suggest something for my application. Also, is a ground control coilover setup really worth it? Thanks guys!
