Progress Tech 02-06 Acura RSX Coil-Over 3 System (FR 425lb / RR 850lb)

Progress Technology is well-known for making solid suspension components, and their CS3/RA coil-over system for the 2002-2006 Acura RSX is a prime example. If you're looking to significantly improve your RSX's handling and responsiveness, this kit is designed to do just that. It features 24 distinct settings for rebound damping, allowing you to really dial in the ride quality and chassis response to match your driving style, whether that's spirited street driving or track days.

The front strut housings are made from seamless steel, CNC machined, and finished with a durable Mil-spec electroless nickel plating. Progress Tech also modified the tie-rod locations to help correct bump steer, which is a notable improvement for handling. The rear threaded sleeves are crafted from stainless steel for longevity, while the aluminum perch adjusters and spring adapters have a clear anodized finish to resist corrosion. These front housings are designed to be taken apart for rebuilding, and the rear dampers can be serviced separately, meaning this system is built to last.

With front springs rated at 425 lb/in and rear springs at 850 lb/in, this coil-over system offers a much firmer and more controlled ride than stock. You can adjust the ride height from 1 to 3 inches lower than factory. The 24-step adjustable rebound damping lets you go from a ride similar to their earlier CS2 systems on the softer settings, all the way up to full rebound for aggressive track use or drag launches. This system is a well-built option for RSX owners serious about performance handling.
