The Progress Tech CS2 coil-over system for 1994–2001 Acura Integra and 1996–2000 Honda Civic/Si applications is a twin-tube low-pressure gas kit tuned for street driving and weekend track days. It uses factory top hats and combines a 550 lb/in front spring with a 450 lb/in rear, providing a 1"–3" lowering range to firm the chassis and enhance cornering while remaining non-adjustable and value-oriented.
