MIA's Description

The Progress Technology Coil-Over System 2 (CS2) is a sport suspension system designed for street performance, track days, and autocross. It features a twin-tube design with deflective disc valving, stainless steel threaded rear sleeves, and CNC locking spring perches. The system includes high-tensile cold-wound springs and foam-type bump stops. It offers a lowering height of 1.0" to 3.0" and allows for 10 different spring rate combinations. The manufacturer states that the damping rates have been successfully used with spring rates up to 650#/inch. These systems are a significant upgrade from OEM or replacement-type OEM damper and spring calibrations, which typically have spring rates around 220#/in front and 110#/in rear. The kit includes two spanners and hardware, but requires OEM steel top hats for installation.
