Show original supplier description
The Rev9 Hyper-Street II coilover kit is a performance lowering solution designed specifically for 2014-2021 Infiniti Q50 V6 RWD models with front ball-type mounts. The system utilizes mono-tube shocks, which provide increased oil and gas capacity compared to stock setups, and features full steel alloy construction with aluminum hardware. It provides 32 clicks of rebound force adjustment, allowing for precise tuning of damping characteristics to suit varying driving conditions. The design allows for independent adjustment of spring tension and ride height, enabling the user to achieve a lower stance without compromising ride comfort or spring tension. Please note that this kit is a dedicated lowering system and will not adjust to factory ride height. Installation by experienced professionals is recommended as no instructions are provided. Compatibility is restricted to RWD models with front ball-type mounting. This kit is not compatible with factory ride height specifications. If the vehicle is equipped with factory adaptive dampers, installation will cause a warning light to illuminate, though the vehicle will remain functional. Additionally, this kit requires a true coilover conversion on the rear strut.
