Öhlins TTX Coilover Kit — Toyota GR Supra (A90/A91) | PHD Spec
Developed and tested by PHD Racing, in collaboration with Öhlins, Eibach, and BBT.
The PHD Spec TTX is not an off-the-shelf part with our name on it. We started with Öhlins TTX dampers — the two-way adjustable, twin-tube platform used in professional motorsport, convertible to four-way — and built a complete kit around them for the A90 chassis: a selected Eibach spring set matched to the damper valving, and a custom top mount assembly designed in collaboration with BBT.
Validated on Öhlins USA's chassis shaker.
The completed kit was run on the 7-post rig at Öhlins USA in North Carolina. That is not a marketing exercise — it means the damping curves and spring rates were measured against the Supra's actual suspension behavior and corrected, rather than estimated from a spec sheet and sorted out later on your car at your expense.
Kit includes:
- Öhlins TTX46 dampers, front and rear
- Eibach spring set F & R
- PHD × BBT custom mounting kit, including BBT front Camber Plates, Front Endlinks, and Rear Upper Mounts.
Fitment: 2020+ Toyota GR Supra A90/A91
** EDC Cancellers are NOT included. Required for aftermarket dampers on EDC-equipped cars — [link your RS-R canceller listing].
