TL-ONE Thunder Lane Single Adjustable Coilover for Nissan 370z and Infiniti G37
TL-ONE Thunder Lane Single Adjustable Coilover for Nissan 370z and Infiniti G37
The TL-ONE coilover system for the Nissan 370z and Infiniti g37 is a purpose-built suspension solution for drivers who demand control, consistency, and confidence—on track, on the street, or in competition.
Designed as a true rear coilover, the TL-ONE improves rear wheel control and balance under load, delivering predictable handling during braking, corner entry, and corner exit. This platform has been proven in real SCCA and NASA Time Trial competition, supporting podium finishes, track records, and season-long reliability.
Spring Rates & Use-Case Options
Each TL-ONE kit is built around your intended use, with proven baseline spring and valving combinations:
- 20k Front / 8k Rear – Track / Race
- 16k Front / 7k Rear – Street / Track
- 14k Front / 6k Rear – Comfort / Performance Street
- 16k Front / 10k Rear – Drift
These are starting points—not off-the-shelf limitations. Every kit is tuned for your vehicle and goals.
Built to Order — Tuned for Your Car
TL-ONE coilovers are built to order.
Before production, we contact you directly to discuss your build and intended use. We tailor spring rate, valving, shock length, and travel using details such as:
- Tire type and size
- Desired ride height
- Vehicle weight
- Sway bar configuration
- Corner weights (when available)
- Driving discipline and experience level
The result is a suspension system that provides clear feedback, usable travel, and consistent performance—without relying on excessive stiffness.
What Makes TL-ONE Different
The TL-ONE platform focuses on platform control and usable damping, not artificial harshness. It’s designed to stay composed under braking, stable through transitions, and predictable as grip and aero load increase.
This is a coilover system meant to evolve with your build—not be replaced.
1-Way Adjustable Kit Includes
- Pillowball / spherical bearing top hats
- 46mm monotube dampers
- Fixed-length shock bodies
- 20-click adjustable rebound damping
- CNC-machined top hats and bottom forks
- Electroplated shock bodies and collars
- Shock body and spring length matched to your desired ride height (to maximize travel)
- Helper springs
All TL-ONE kits are fully rebuildable, serviceable, and re-valvable.
Customization & Upgrade Options
Available options include:
- Digressive valving profile
- Linear valving profile
- Linear compression with digressive rebound
- Swift springs
- Custom spring rates
- Custom spring lengths
- Custom helper spring lengths
All TL-ONE kits are upgradeable to a 3-way adjustable system with remote reservoirs, featuring:
- 34-click low-speed compression adjustment
- 24-click high-speed compression adjustment
Proven in Real Competition
TL-ONE coilovers have been validated in real-world use—from weekend-driven SCCA Tuner cars to record-setting max-effort Time Trial builds. Proper damping, thoughtful setup, and usable travel make a measurable difference on track.
If you’re looking for a 370z / g37 coilover system that delivers confidence, consistency, and long-term value, the TL-ONE is engineered for exactly that.
Frequently Asked Questions
What does “true rear” coilover mean on a 370z/g37?
A true rear coilover places the spring and damper together at the rear wheel, improving motion ratio, rear wheel control, and predictability under load compared to divorced spring setups.
Are TL-ONE coilovers street drivable?
Yes. Spring rates and valving are selected based on your intended use. Street/Track and Comfort setups prioritize compliance and control, not harshness.
Do I need to know my corner weights before ordering?
No. Corner weights are helpful but not required. We can tune the kit using vehicle weight, tire size, ride height, and sway bar configuration. Corner weights can be addressed later during alignment.
Are these off-the-shelf coilovers?
No. Every TL-ONE kit is built to order. Shock length, spring length, rates, and valving are tailored to your car and goals.
Can I change spring rates later?
Yes. All TL-ONE kits are fully rebuildable and re-valvable, allowing the suspension to evolve as your build changes.
What type of driving are these designed for?
TL-ONE coilovers are commonly used for SCCA & NASA Time Trials, track days, street-driven performance cars, and drift applications.
Can I upgrade later to remote reservoirs?
Yes. All TL-ONE kits are upgradeable to a 3-way adjustable system with remote reservoirs.
