Öhlins TTX Pro Suspension System for Porsche 911 GT3 / GT3 RS (991.1 & 991.2, 2014–2019)
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.
Two versions

- POF MR00S2 – 911 GT3 RS (991): 120 N/mm front (48120-21) / 200 N/mm rear (48140-37), 15 mm target ride-height reduction.
Kit contents
