Honda Civic ED/EF Coilovers - TL-ONE - One Way Adjustable

Build a suspension setup around your Honda Civic ED or EF with ThunderLane 1-way coilovers, custom spring rates and application-specific valving.

For an ED or EF project, engine changes, weight reduction and tyre choice are useful parts of the suspension brief. We consider these alongside your ride height and intended use, whether the car is a road build, a track-day project or prepared for competition.

Why choose ThunderLane Honda Civic ED/EF coilovers?

Custom spring rates and damper valving

The spring and damper package is specified together using your vehicle details and driving requirements. This establishes a baseline for your application before you begin fine-tuning the car.

20-way rebound adjustment

Twenty rebound settings let you refine the damper response from the chosen baseline. A single rebound adjuster keeps the tuning process straightforward while the underlying spring and valving specification is selected around your application.

Tested, serviceable and rebuildable

Every damper is individually dyno tested before dispatch. Rebuildable construction allows servicing, repairs and revalving as the suspension wears or the requirements of your car change.

Key features

• Custom spring rates and application-specific damper valving
• 20-way rebound adjustment
• Microcellular polyurethane bump stops for progressive support near the end of the suspension travel
• Electroplated damper bodies for corrosion resistance
• Fully rebuildable and revalveable dampers
• Individual damper dyno testing before dispatch
