The GR86/GT86/BRZ TL-ONE Grip Kit is Thunder Lane's complete suspension solution for the shared Toyota/Subaru chassis — hand-assembled in Poland, pairing TL-ONE coilovers with adjustable front and rear sway bars so roll stiffness, spring rate, and damping all work as one system instead of mismatched parts.
Built for Racing, Time Attack, Autocross, and HPDE
Rather than relying on excessive spring rate, the Grip Kit is built around usable suspension travel and controlled roll stiffness so the car generates grip earlier and stays balanced mid-corner. 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
- TL-ONE monotube coilovers, front and rear
- 20-click rebound adjustment (application-specific)
- Ride Height Adjustment (fixed-length shock bodies preserve travel)
- Front and rear adjustable sway bars with adjustable end links
- Pillowball/spherical bearing upper mounts
- CVP + PVP dyno graphs included with every kit
Construction & Hardware
Check valves manage the split between compression and rebound for strong low-speed control without sacrificing bump compliance. Electroplated shock bodies and collars resist corrosion, and the full kit is rebuildable, serviceable, and re-valvable as tires, alignment, or focus change.
Fitment
Toyota GT86 (ZN6), Toyota GR86 (ZN8), Subaru BRZ (ZC6 & ZD8) — all share suspension architecture, tuned per generation.
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 include sway bars with the coilovers?
Sway bars let roll stiffness be tuned independently of spring rate, improving grip and balance without sacrificing ride quality or travel.
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.
