Description

The RS-R Superdown SUS springs are engineered to provide a lowered stance and enhanced handling for your Infiniti Q50. These springs are meticulously designed with the factory suspension geometry, shock dampening, spring rate, and ride height levels in mind, ensuring both performance and comfort. RS-R aims to fulfill your needs to lower your car and improve its handling. These Superdown springs are designed for the 2016-2024 Infiniti Q50 3.0t Sport, RedSport 400, and SilverSport RWD models with the V37 chassis code. They provide an approximate drop of -40mm to -45mm (or -1.6in to -1.8in) in both the front and rear, significantly reducing the fender-to-wheel gap. The spring rates for this application are 8.93kg/mm in the front and 3.67kg/mm in the rear. This setup is tuned for the track or the road, offering a balance between sporty performance and everyday drivability.
