The BMW F22 2 Series TL-ONE Coilover System is Thunder Lane's track-focused single-adjustable coilover for the F22 2 Series — hand-assembled in Poland and bespoke-valved to your car, tires, and goals. Every set ships with inverted front struts and rear shocks, 20-click rebound adjustment, adjustable end links, and dual height adjustment.
Built for Racing, Time Attack, Autocross, and HPDE
The F22's stiff shell and rear-drive balance reward a coilover that controls weight transfer without going harsh. TL-ONE is valved around that balance, and 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 front struts and rear shocks, rebuildable monotube design
- 20-click rebound adjustment (1-way)
- Dual height adjustment; front and rear adjustable end links included
- Camber top-hat options (3-bolt and 5-bolt); pillowball or rubber upper mounts
- Spring rates finalized in consultation with you before production begins
- Digressive valving; CVP + PVP dyno graphs included with every kit
Construction & Hardware
Inverted front struts increase rigidity under load and reduce unsprung weight, while check valves manage the split between compression and rebound for strong low-speed platform control. Every damper is electroplated for corrosion resistance and is fully rebuildable, serviceable, and re-valvable as tires, alignment, or use case change.
Fitment
BMW 2 Series (F22), including 228i, M235i and M240i, 2014–2021.

What's the warranty?
6 months — void for track damage, covers unreasonable wear and defects only.
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.
