Product Description

The RS-R F668W Down Sus Lowering Springs are engineered specifically for the 2015-2017 Subaru Outback 2.5 (BS9), offering a front drop of 1.2-1.4 inches and a rear drop of 1.4-1.6 inches. Matched spring rates of 3.90 kg/mm front and 3.93 kg/mm rear keep the Outback's ride composed and balanced, reducing body roll and tightening handling response without the harshness associated with more aggressive lowering setups.

Designed as a direct OEM replacement, these springs install onto the factory struts and shocks without any additional modifications. The powder-coated finish ensures long-term durability against the elements, making them well-suited for year-round driving. Backed by a 3-year / 36,000-mile warranty, the RS-R F668W is the ideal choice for Outback owners seeking a subtle, functional drop with genuine JDM-quality construction.
