Ohlins 911 GT3 RS (991) TTX-PRO Pro-level Performance

The Öhlins TTX Pro Coilover System for the Porsche 911 GT3 RS (991) is a purpose-built circuit suspension package for one of the most track-capable road cars in production. Developed around Öhlins' TTX — Twin Tube eXtreme — technology, the kit channels Öhlins' experience from Formula 1, IndyCar, and MotoGP into a bolt-on coilover system that raises damping performance well beyond what the factory chassis management system is capable of providing.

TTX technology uses a twin-tube damper architecture in which an inner working tube and outer reserve tube regulate fluid flow with high precision. Fully independent compression and rebound adjusters allow separate tuning of each damping phase, enabling the driver or engineer to optimize the car's behavior for a specific track, surface, or tire. The system is also upgradeable to three or four-way adjustability for more advanced setup capability.

Öhlins' temperature-compensating design ensures damping output remains consistent as fluid temperatures climb during intensive track use. For the GT3 RS — a car designed to be driven at the limit — that thermal stability translates directly into repeatable lap times and predictable chassis behavior.

Ride height is set approximately 20mm below standard. The system does not function with the factory PASM lift system, and ride height adjustment is independent of spring preload to preserve the engineered spring characteristics.
