Progress Tech's highly-regarded Acura RSX Progress Tech Coil-over system has been updated and released as a new CS3/RA rebound-adjustable system! The "sporty" Progress ride quality has been further enhanced with 24 adjustable damper settings to dial in the ride and responsiveness of your DC5. These CS3 Coil-over kits are perfect for the performance-minded enthusiast wanting to improve handling, control & vehicle response. The new 24-way adjustable dampers are aggressively tuned for wide range of ride control and enhanced handling capability. The seamless steel front strut housings are CNC machined and precision-fabricated, then plated with an attractive and durable Mil-spec electroless nickel finish. The tie-rod locatons have been modified for bump steer correction. The rear threaded sleeves are stainless steel. The aluminum perch adjusters and spring adapters are clear anodized for durability. Our exclusive take-apart front housings are rebuild-able and the rear dampers are available as service parts (only). What is the CS3/RA all about? Tune your ride! You can easily adjust your rebound damping to your preferred settings, and fine-tune the ride and chassis response. The soft setting range is similar to our earlier CS2. The rebound settings have been developed with 24 linear steps up to full rebound, plenty for your track days! This means that the CS3 has our characteristic "sporty" ride on softer settings. Turn up the rebound settings for higher spring rates, track days or some quick 1/4 mile drag launches
