Product Description

The RS-R F666W Down Sus Lowering Springs are performance-oriented springs designed for **2015-2019 Subaru Outback 3.6R AWD** vehicles. These springs lower the ride height by roughly **30 mm to 35 mm (about 1.2"-1.4")** at both the front and rear compared to stock suspension, giving the Outback a more aggressive stance and improved handling characteristics. The tuned spring rates help reduce body roll and improve cornering precision while maintaining a balanced ride quality for daily driving.

Installation involves replacing the factory springs with the RS-R set at each corner. After installation, a professional wheel alignment is recommended to ensure proper suspension geometry, tire wear, and handling performance. The durable construction and engineered spring rates make this kit a solid choice for owners who want a sportier look and improved dynamic feel without installing full coilovers.
