Ohlins Cayman GT4 (981) TTX-PRO Pro-level Performance

The Öhlins TTX Pro Coilover System for the Porsche Cayman GT4 (981) is a race-developed suspension package built for a car that already sets a high standard for mid-engine handling. Engineered around Öhlins' TTX — Twin Tube eXtreme — technology, the kit applies the same damping principles Öhlins brings to Formula 1, IndyCar, and MotoGP to deliver a level of chassis control that no factory option can match.

TTX technology uses a twin-tube damper architecture where an inner working tube and outer reserve tube regulate fluid flow across the full range of track driving conditions. Fully independent compression and rebound adjusters allow the driver or engineer to separately tune each damping phase, enabling setup changes that a single-adjuster system cannot provide. The system is upgradeable to three or four-way adjustability for advanced setup requirements.

Öhlins' temperature-compensating design maintains consistent damping characteristics as fluid temperatures rise during sustained track sessions. For the Cayman GT4 — a car that rewards balance and precision — that consistency is essential to unlocking the platform's full potential.

Ride height adjustment is kept independent of spring preload, allowing clean corner-weight and rake adjustments without altering spring behavior or reducing usable suspension travel.
