How does the 'Active' damping feature work?

The Best-i Active coilovers use an electronic control unit (ECU) that reads your vehicle's speed. Based on this input, it automatically adjusts the damping force of the shocks to provide a comfortable ride at lower speeds and firmer control during spirited driving. You can also manually select from 32 different damping settings.

What is included with the RS-R Best-i Active Coilovers?

This kit includes the complete front and rear coilover assemblies, the electronic control unit (ECU), a controller for manual adjustments, and necessary wiring for the speed sensor integration. Refer to the product documentation for a full list of included components.

Do I need any special tools or parts for installation?

Installation involves replacing the factory strut and spring assemblies. You will need standard suspension tools. Proper wiring of the ECU to the vehicle's speed sensor signal is crucial for the active damping function, so referring to the manufacturer's detailed installation manual is highly recommended.

Product Details

If you're looking to fine-tune your 2014+ Lexus RC-F (USC10) for track days or spirited street driving, the RS-R Best-i Active Coilovers offer an advanced solution for adjusting ride height and damping. These coilovers are designed to give you precise control over your suspension's performance, allowing you to dial in the perfect setup for your driving style and conditions. They replace your factory struts and springs, providing a more integrated and adjustable system.

What sets the Best-i Active system apart is its integrated electronic control unit (ECU) and vehicle speed sensor compatibility. This allows the coilovers to automatically adjust damping force based on your driving speed and road conditions, offering a comfortable ride during normal cruising and firmer, more controlled damping when you're pushing the car harder. You can also manually select from 32 different damping levels using the included controller, giving you granular control over your suspension's feel. The spring rates are carefully chosen to complement the RC-F's performance characteristics, providing a solid foundation for improved handling without sacrificing too much ride comfort. The bodies are constructed from durable aluminum, helping to reduce unsprung weight and resist corrosion.

Installation involves replacing the entire front and rear strut assemblies. The electronic control unit needs to be wired into the vehicle's speed sensor signal, which is a critical step for the active damping feature to function correctly. It's recommended to consult the included installation manual for detailed instructions on wiring and setup. These coilovers are a significant upgrade for RC-F owners seeking a high level of adjustability and performance from their suspension.
