CS3 Coilover System

The Progress Coilover System 3 (CS3) with part number 78.0102 is an updated suspension component for the 2002-2005 Acura RSX (DC5 chassis). This system offers 12 linear rebound adjustment settings, allowing enthusiasts to precisely dial in their vehicle's ride quality and responsiveness for various driving conditions, from street performance to track days. The CS3 system utilizes twin-tube dampers with deflective disc valving and includes shortened front housings for increased wheel travel. The tie-rod locations have been modified to correct bump steer, and the rear threaded sleeves are constructed from stainless steel for durability. Front strut housings are CNC machined, precision-fabricated, and plated with a Mil-spec electroless nickel finish. Aluminum perch adjusters and spring adapters are clear anodized. Available spring rate combinations include "Street-Sport" with 350 lb/in front and 650 lb/in rear springs, designed as a compromise for ride quality and handling, and "Autocross-Track" with 425 lb/in front and 850 lb/in rear springs for a more aggressive, track-focused setup. The "Street-Sport" setup is noted as being harsher than OEM but fun for spirited driving, while the "Autocross-Track" setup offers more grip and faster chassis response but is not recommended for poor weather conditions or inexperienced drivers. A crucial installation requirement is that this kit reuses the OEM steel top hats; the black OEM top hats are not included. Progress Race springs are wound using high-tensile spring wire.
