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. Every kit is received at PHD Racing, modified to the Supra specification, and then shipped to you.
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, with separate compression and rebound adjusters
- Eibach main and helper spring set, front and rear, to PHD specification
- PHD × BBT custom mounting kit, including BBT front camber plates, front end links, and rear upper mounts
Fitment: 2020+ Toyota GR Supra A90/A91.
EDC cancellers are NOT included. Supras with the factory adaptive (EDC) suspension need a cancellation kit to avoid fault codes — see our Öhlins EDC Cancellation Kit 35020-30.
