Develop a suspension setup for your BMW G87 around the way you use it, with ThunderLane 1-way coilovers and bespoke spring and damper specifications.

Tell us whether your priority is road use, regular track days or competition, and how the car has been modified. We use your tyre setup, ride height and vehicle details to establish a specification that supports those priorities.

Why choose ThunderLane BMW G87 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
