BMW E30 Coilovers - 1 Way Inverted

Build your BMW E30 suspension around the complete car with ThunderLane 1-way inverted coilovers, custom spring rates and application-specific damper valving.

An E30 project can change substantially as its engine, interior, wheels and suspension are developed. Tell us what has changed and how you plan to use it, so the spring and damper specification reflects the finished build.

Why choose ThunderLane BMW E30 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 damper construction

This inverted kit is specified for the listed application. We confirm the vehicle details and existing suspension configuration before production.

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
