RS*R XLIN145MA Best-i Active Coilover System for 2016+ Infiniti Q50 Red Sport AWD

The RS*R Best-i Active Coilover System is a premium hand-assembled monotube suspension upgrade designed specifically for 2016 and newer Infiniti Q50 3.0t Red Sport 400 AWD models. This innovative coilover system maintains full compatibility with the factory Dynamic Digital Suspension (DDS) system, allowing you to retain all factory adaptive damping controls while enjoying the benefits of aftermarket suspension tuning.

Key Features:

• Fully compatible with factory Dynamic Digital Suspension (DDS) - damper adjustments controlled through factory AVS controller
• Unique dual adjustment system: 36-way factory electronic adjustment plus secondary 24-way manual adjustment dial at coilover base
• Hand-assembled monotube damper construction for superior quality and consistency
• Premium components including urethane top mount bushings, rubber spring pads, and roller bearings
• Front spring rate: 10 kg/mm | Rear spring rate: 5 kg/mm
• Height adjustable front: -10mm to -65mm (-0.4 to -2.6 inches) recommended range
• Height adjustable rear: -20mm to -65mm (-0.8 to -2.6 inches) recommended range
• Maximum adjustment range: Front 0 to -85mm | Rear 0 to -100mm

RS*R engineers have carefully calibrated this system to balance performance handling with daily driving comfort. Unlike standard aftermarket coilovers that disable factory electronic damping systems, the Best-i Active series preserves the OEM actuators and control logic, allowing seamless integration with your Q50's adaptive suspension modes. Backed by a 1-year or 12,000-mile limited warranty from RS*R.
