Description

The RS-R Super Down Springs (N145S) are engineered to provide a significant drop in ride height for a more aggressive stance and improved handling dynamics. The approximate drop achieved with these springs is -40mm to -45mm (-1.6in to -1.8in) for both the front and rear of the vehicle. With a front spring rate of 8.90kg/mm and a rear spring rate of 3.70kg/mm, these springs are tuned to reduce body roll and enhance responsiveness during cornering and acceleration. This setup aims to deliver a sporty feel without overly compromising ride quality. The RS-R Super Down Springs are backed by a 3-year or 36,000-mile warranty from the day of purchase, offering peace of mind for the original purchaser. Fitment is crucial for this product, and it is specifically designed for 2016+ Infiniti Q50 AWD models, including the Red Sport 400 and Sport 30t trims. It is recommended to confirm fitment with a sales representative before purchasing to avoid potential compatibility issues.
