Öhlins TTX Pro Suspension System for Porsche Cayman GT4 / 718 Spyder (981 & 982, 2016–2025)
Öhlins TTX Pro is the apex of Öhlins' automotive range: twin-tube, solid-piston dampers drawn directly from the company's Formula 1, IndyCar and MotoGP programs, with separate compression and rebound adjusters on every corner. Pressure-balanced design eliminates cavitation for consistent, fade-free damping lap after lap. Rebuildable and revalvable through Öhlins USA.
With Öhlins' Road & Track GT4 system discontinued for 2026, TTX Pro is now the Öhlins system for the GT4 and Spyder.
