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

The Öhlins TTX Pro Coilover System for the Porsche Cayman GT4 CS (981) is a motorsport-grade suspension package developed specifically for the Cayman platform's track-focused architecture. Built around Öhlins' TTX — Twin Tube eXtreme — technology, the kit brings the same damping principles Öhlins applies in Formula 1, IndyCar, and MotoGP to a bolt-on system that transforms the GT4 CS into a precisely tunable circuit tool.

TTX technology uses a twin-tube damper architecture where an inner working tube and outer reserve tube manage fluid flow across a wide range of shaft speeds with high precision. Independent compression and rebound adjusters allow separate control of each damping phase — a significant advantage for a car with the GT4 CS's suspension geometry and spring rates. The system is upgradeable to three or four-way adjustability for advanced setup requirements.

Öhlins' temperature-compensating design keeps damping output consistent as fluid temperatures rise through extended track use. The Cayman GT4 CS is already a capable circuit car in standard form; the TTX Pro system allows a driver or engineer to unlock its full potential through precise chassis tuning.

The kit targets a ride height reduction of approximately 20mm below OE. Ride height adjustment is independent of spring preload, enabling clean geometry and corner-weight adjustments without altering spring behavior.
