Factory set of coil springs off of a 2006 BMW Z4 with a 6-Speed manual transmission and the sport package suspension. These will fit all 2003-2008 BMW Z4's except for M models. These are the sport springs that were available only on certain package models. If your car did not have the sport springs from factory then these springs may affect ride height and stiffness due to the spring rate change. The rear springs have 3 green indicator dots, as shown in the last photo. The springs are in good overall condition with just the typical scratches and wear on the paint.
