BMW E46 Coilovers - TL-ONE - Inverted One Way Adjustable

Upgrade your BMW E46 with ThunderLane 1-way inverted coilovers, built to order with spring rates and damper valving selected specifically for your car.

Your E46's engine configuration, vehicle weight, tyres, modifications and intended use all help define the suspension brief. Whether you are planning road use, track days or competition, we develop the specification around those requirements.

Why choose ThunderLane BMW E46 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.

Inverted front struts and upside-down rear dampers

The E46 kit uses inverted front struts and an upside-down rear damper layout. These are combined with the spring rates and valving selected for your individual build.

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
