The MQB Platform TL-ONE Coilover System is Thunder Lane's track-focused single-adjustable coilover for the shared Volkswagen/Audi MQB platform — hand-assembled in Poland with inverted front struts and inverted rear shocks for consistent damping under hard use.
Built for Racing, Time Attack, Autocross, and HPDE
The MQB platform rewards a coilover that keeps the front end loaded through trail-braking — TL-ONE's low-speed control is valved around that, and adjustable front sway bar end links are included to help balance the platform. Every kit can also be valved specifically for street use — the compliance needed for competent track use often makes for a comfortable street ride, since controlling the platform better also controls body motion better on the street.
Technical Specs
- Inverted monotube dampers, 36mm piston / 40mm body, with advanced piston technology and check valves
- 20-click rebound adjustment (1-way)
- Independent Ride Height and Travel Adjustment
- 2.5" linear springs, customizable rates (Swift optional)
- Spherical bearing top mounts, adjustable front sway bar end links included
- CVP + PVP dyno graphs included with every kit
Construction & Hardware
Inverted strut design increases rigidity under load and improves durability over repeated track sessions. Electroplated bodies resist corrosion long-term, and every damper is fully rebuildable with individual replacement parts available.
Fitment
Built for the shared Volkswagen/Audi MQB platform, including VW Golf/GTI/Golf R (Mk7/7.5, 2012–2020) and Audi S3, RS3, TT, TT RS, and TTS — exact sub-model and generation confirmed during the build.
Frequently Asked Questions

4–6 weeks, built to order.
What's the warranty?
6 months — void for track damage, covers unreasonable wear and defects only.
Does this fit Audi models too?
Yes — this kit is built for the shared VW/Audi MQB platform, covering the VW Golf/GTI/Golf R as well as Audi S3, RS3, TT, TT RS, and TTS. We confirm your exact sub-model and generation during the build.
Do you include dyno graphs?
Yes — CVP + PVP graphs with every order.
Is this streetable?
Yes — every kit can be valved specifically for street use if that's your preference. Even with track-oriented valving, the compliance needed for competent track use often makes for a comfortable street ride, since controlling the platform better also controls body motion better on the street.
