Koni 8245-1255 Special Active Rear Shock Absorber - Twin-Tube Low Pressure Gas, Red

The Koni 8245-1255 Special Active is a rear shock absorber from the premium KONI 8245 Red Series, engineered as a twin-tube, low-pressure gas design. Built for Porsche 911 (996) Carrera models (excluding GT2, GT3, and PASM-equipped vehicles), this shock delivers a sophisticated balance of performance handling and everyday ride comfort without compromise.

At the heart of the Special Active is KONI's patented Frequency Selective Damping (FSD) technology — an advanced passive system that automatically adapts damping force in milliseconds based on road surface and driving conditions, all without electronics. Under spirited driving on smooth roads, the damper firms up for precise body control and cornering grip. Over rough pavement, expansion joints, and transverse ridges, it softens to absorb impacts and smooth the ride.
