String Theory Garage will be closed to the public from Wednesday, 29th July to Thursday, 6th August for our annual shutdown.
If you need to get in touch, please leave us a voicemail or send an email. Our team will happily get back to you when we return on Friday, 7th August.
Shopping online? Don't worry! Our online store will remain active! We hope to ship orders placed for in-stock items as normal during the shutdown. Anything else will be dealt with upon our return.
Thank you for your understanding, String Theory Garage Team
The Ohlins TTX is the motorsport-specification suspension kit for 718 Cayman GT4 owners who use their car at the sharp end of track day and competition driving. Built around the TTX (Twin Tube X) platform with 2-way independent adjustment, this kit gives you separate control of compression and rebound — the level of adjustability that a car of the GT4's ability truly warrants.
This is the kit we recommend when the Road & Track DFV isn't enough — for drivers who corner-weight their car, run semi-slick or slick tyres, and want to extract the last meaningful improvement from their chassis setup.
Adjustment: Independent compression and rebound control
Height adjustment: Yes — approximately 20mm below standard as baseline, fully adjustable spring perch
Rebuild service: Available through String Theory Garage and Ohlins UK
SKUs: POF 5Q00 (front) / POF 6N01 (rear)
Fitment
Compatible with: Porsche 718 Cayman GT4 (982), years 2020–2021.
For road-biased or mixed-use setups, the Ohlins Road & Track DFV may be a better fit. Contact us to discuss your specific use case and we'll recommend the right kit.
Price: £7,900 | Available to order — lead time typically 5–10 working days. Professional fitting, corner-weighting and alignment available at our premises.
