Ohlins Advanced Trackday TTX Coilovers (Track Day Version) — Porsche 991 GT3 RS
The Ohlins TTX is the suspension of choice for Porsche 991 GT3 RS owners who use their car seriously on track. Built around Ohlins' TTX (Twin Tube X) technology, this is a motorsport-grade coilover kit that delivers the level of precision, consistency and adjustability that a car of the GT3 RS's ability demands.
This is the Track Day version — calibrated for road-legal track use, where you need the car to be manageable and consistent across a full day of circuit driving, not just fast for three laps. If you're looking at the Motorsport version, that kit is tuned for pure performance with less concession to comfort or longevity between rebuilds.

Track Day vs Motorsport — which should I choose?
The Track Day version uses damper valving calibrated for road-legal tyres and a full day of track use. If you run your GT3 RS on track days — including events on Michelin Cup 2s or similar semi-slicks — this is the correct kit. The Motorsport version uses stiffer valving suited to slick tyres and sprint/endurance racing environments where harshness is irrelevant.

Why TTX?
The TTX platform uses a twin-tube design that separates the damping and spring functions more cleanly than a conventional monotube, resulting in better thermal stability during sustained track use. For a GT3 RS being pushed hard over a full day, that consistency matters enormously — the car behaves the same at the end of a session as it did at the start.
