The Supra A90 TL-PRO Coilover System is Thunder Lane's flagship true 3-way adjustable coilover for the Toyota GR Supra A90 — hand-assembled in Poland for drivers who demand maximum control, consistency, and tuning flexibility, whether the build is track-focused or a serious street/track dual-duty setup.
Built for Racing, Time Attack, Autocross, and HPDE
Independent rebound, low-speed compression, and high-speed compression let you tune mechanical grip and platform support without introducing unnecessary harshness — critical for high-grip tires and long track sessions. 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 inverted rear shocks, 36mm piston / 40mm body
- 20-click rebound, 34-click low-speed compression, 18-click high-speed compression (true 3-way)
- Independent Ride Height and Travel Adjustment
- External compression canisters with quick disconnects, trunk-friendly mounting
- 2.5" linear springs, customizable rates
- CVP + PVP dyno graphs included with every kit
Construction & Hardware
Inverted front struts and rear shocks increase rigidity under load and reduce unsprung weight at the rear by moving the shock body to the body-side. Check valves manage the split between compression and rebound for strong low-speed platform control, and every damper is fully rebuildable, serviceable, and re-valvable.
Fitment
Toyota GR Supra A90, all trims.
Frequently Asked Questions
What's the lead time?
4–6 weeks, built to order.
What's the warranty?
6 months — void for track damage, covers unreasonable wear and defects only.
Why does this kit use remote reservoirs?
Remote reservoirs increase oil volume and improve heat management, maintaining consistent damping during long track sessions, with quick disconnect fittings for clean trunk installation.
Can spring rates and hose length be customized?
Yes — spring rates, valving style, and reservoir hose length are selected during the build.
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.
