Product Description

The RS-R N148D Down Sus Lowering Springs are a precision suspension upgrade designed for the **2017-2022 Infiniti Q60** with rear-wheel drive, including Sport, Red Sport, and Silver Sport trims. These springs provide a moderate lowering - approximately **20-25 mm at the front** and **30-35 mm at the rear** - giving your Q60 a more aggressive stance and lower center of gravity for improved handling and reduced body roll.

Engineered with tuned spring rates (11.22 kg/mm front and 4.41 kg/mm rear), the N148D set works with the vehicle's stock suspension geometry and shock absorbers to enhance cornering response and stability without overly compromising ride quality. The durable powder-coated finish helps protect against corrosion and road wear, making these springs suitable for both daily driving and spirited street performance.

This kit includes all four lowering springs required for installation. After installation, a professional wheel alignment is recommended to ensure optimal suspension geometry and even tire wear. Coverage is confirmed for **2017 through 2022 Infiniti Q60 RWD** models; fitment beyond 2022 is unconfirmed at the time of this listing.
