Product Description

The Ohlins POR GN01S1 is a Road & Track coilover suspension system for the 1988-1994 Porsche 911 (964) in Carrera 2, Carrera 4, Speedster, and Turbo variants across all body styles -- Coupe, Targa, and Cabriolet. It is a complete four-corner kit containing upside-down McPherson front struts and conventional rear shock absorbers, both with matched springs, all mounting hardware, and adjustable aluminum top mounts at the front with camber adjustment capability.

The system is built around Ohlins' patented DFV (Dual Flow Valve) technology -- a single external adjuster simultaneously changes high-speed and low-speed compression and rebound, allowing the driver to transition between a compliant street setting and a firm track setting quickly and without tools. Front spring rate is 50 N/mm; rear is 90 N/mm. Both ends deliver 20mm of lowering at the recommended setting with ±15mm of additional ride height adjustment available independently of spring preload, so ride height and damping can be tuned without affecting each other. The shocks are fully rebuildable through Ohlins' dealer service network and are corrosion tested to ISO 9227. TUV certified for road use. Backed by Ohlins' 2-year limited warranty.
