Honda Civic EK/EJ/EM Coilovers - TL-ONE - One Way Adjustable

Develop your Honda Civic EK, EJ or EM suspension around your build with ThunderLane 1-way coilovers, made to order with custom springs and valving.

Tell us about the car's current specification and the balance you want from it. From road use to circuit preparation, we consider your tyres, vehicle weight, modifications and intended ride height before settling on the spring and damper setup.

Why choose ThunderLane Honda Civic EK/EJ/EM 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
