I'm not sure on a chart. I have an HDK k member with Summit brand coil overs. I went with the recommended 450# springs. It's great on the street. I spoke with Denny not to long ago. He recommended 300# springs for my Dart. I haven't put them on yet though. I would give Denny a call and see what he says.
