The Progress Tech CS2 coil-over system for 1994–2001 Acura Integra and 1996–2000 Honda Civic/Si applications is a non-adjustable twin-tube low-pressure gas kit tuned for street performance. It fits with factory top hats and combines a 350 lb/in front spring with a 450 lb/in rear, delivering a 1"–3" lowering range that sharpens handling and improves traction without adjustable damping controls.
