The Mustang S550/S650 TL-PRO Coilover System (2015+) is Thunder Lane’s flagship true 3-way adjustable coilover for the Ford Mustang — hand-assembled in Poland and built for serious track use: time attack, endurance, and high-grip street/track builds where repeatable damping control and thermal stability matter.
Built for Racing, Time Attack, Autocross, and HPDE
Independent 3-way damping adjustment lets you tune chassis platform separately from bump compliance — rebound for balance and response, low-speed compression for braking/roll/pitch, and high-speed compression for bumps and curbing. 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
- Front inverted struts (36mm piston), rear dampers (46mm piston)
- 20-click rebound, 34-click low-speed compression, 18-click high-speed compression (true 3-way)
- Ride Height Adjustment (fixed-length damper)
- Front camber plates, rear remote compression canisters with quick disconnect
- Track baseline springs: Front 10–12kg / Rear 16kg (customizable)
- CVP + PVP dyno graphs included with every kit
Construction & Hardware
Rear remote compression canisters increase oil volume for better heat management and damping consistency under sustained track load, with quick-disconnect fittings for clean mounting and easy service. Front camber plates give alignment flexibility, and every damper is rebuildable, serviceable, and re-valvable.

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.
What does 3-way adjustment control?
Rebound tunes response and balance, low-speed compression controls chassis platform (roll/pitch), and high-speed compression manages bumps and curbing.
Do the canisters require permanent mounting?
No — quick disconnect fittings simplify installation and service.
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.
