RS-R Best-i Active Coilovers for 2017-2022 Infiniti Q60 Sport/Red Sport AWD (3.0T) (1.0in Front / 1.2in Rear)

Fits the 2017-2022 Infiniti Q60 Sport AWD and the 2017-2022 Infiniti Q60 Red Sport 400 AWD (3.0T) equipped with factory Digital Dynamic Suspension (DDS).

The RS-R Best-i Active series is engineered specifically for the V37 chassis Q60 to maintain full compatibility with the factory electronic adaptive suspension. Unlike standard aftermarket systems that require deleting the electronic damping controls, the Best-i Active utilizes an integrated electro-magnetic valve that plugs directly into the OEM DDS/AVS harness. By transferring your factory actuators to these RS-R dampers, you retain full functionality of the cabin drive mode selector while gaining the precision, heat management, and height adjustability of a professional-grade mono-tube coilover system.

These coilovers are built with Ti2000 titanium-composite springs, which offer superior resistance to sag and significant weight savings over traditional steel. The mono-tube internal design ensures consistent damping performance during aggressive driving by dissipating heat more efficiently. For refined ride quality, the kit features laser-cut steel upper mounts with rubber padding and urethane bushings to minimize vibration and cabin noise. Integrated silent roller bearings eliminate the "spring ping" noise often associated with steering rotation.

Installation is a direct bolt-on process requiring the transfer of factory actuators. A professional 4-wheel alignment is mandatory after installation to ensure proper tire wear and handling geometry. This kit is designed strictly for AWD models; it does not fit RWD vehicles or those without factory electronic suspension.
