Which spring rate do I need?

Your ideal spring rates are determined based on vehicle weight, which should take into account any modifications that have been made. One step softer or firmer than the recommended street spring rate can be considered, depending on the purpose of the car (softer for drag racing, firmer for autocross, etc.). See our article Calculating Spring Rate for QA1 Stock Mount Coil-Over Systems to determine your ideal spring rate.
