Selling a used set of Swift Spec-R springs for BMW E82 1 series. These were the highest spring rate lowering springs available for the E82 but have been discontinued by Swift and are no longer available new. Description from Swift below: BUILT FOR TRACK DUTY, SWIFT SPEC-R SPRINGS ARE DESIGNED AT THE UPPER LIMITS OF THE OEM SHOCK VALVING. TRACK TESTED AND TUNED FOR OPTIMUM PERFORMANCE YET COMFORTABLE ENOUGH FOR A DAILY DRIVER. From HPDE events to SCCA competition, Swift Spec-R Sport Springs are made for the track enthusiast looking to take their vehicle to the next level. Swift Spec-R Sport Springs were engineered with 3 characteristics in mind. Modified ride height compared to Sport Springs to maximize optimal suspension geometry. Further increasing the spring rate to enhance overall performance. The increase in spring rate is based on the upper limits of the vehicles factory shock valving. Maintaining optimal comfort level for street use. Spec R springs are wound with the same engineering and material as our sports springs. With the exception of stiffer rates and slight change in ride height; you can expect the same characteristics as our sports springs.
