The Öhlins TTX Pro Coilover System for the Porsche 911 GT3 (991) delivers race-level damper performance for a car engineered from the factory to pursue lap times. Built around Öhlins' TTX — Twin Tube eXtreme — technology, the kit draws on Öhlins' active involvement in Formula 1, IndyCar, and MotoGP to provide suspension capability that goes significantly beyond the factory PASM system.
TTX technology uses a twin-tube damper architecture where an inner working tube and outer reserve tube regulate fluid flow with high precision across the full range of shaft speeds encountered in track driving. Fully independent compression and rebound adjusters allow separate tuning of each damping phase — a key advantage over single-adjuster systems when optimizing for a specific circuit or tire compound. The system is upgradeable to three or four-way adjustability for more advanced setup requirements.
Öhlins' temperature-compensating design maintains consistent damping output as fluid temperatures rise during sustained track use. For the GT3 — a car that rewards precise chassis balance — that consistency is the difference between a good lap and a great one.
Ride height is set approximately 20mm below standard, with adjustment kept independent of spring preload so that height changes do not alter spring characteristics or reduce suspension travel.
