The Progress Technology CS2 Coil-Over 2 system for 1990–1993 Acura Integra is a non-adjustable, twin-tube low-pressure gas kit tuned for daily driving, street performance and track-day use. It uses the factory top hat for fitment, delivers front/rear spring rates of 350/250 lb/in and provides roughly 1–3 inches of lowering for a firmer, more planted ride without adjustable dampers.
