BC Racing DS Series Coilovers - 2015 WRX STI / Swift Spring Upgrade / 9k Front / 8k Rear

The BC Racing F-25-DS-9K-8K-SW is a high-performance DS Series coilover system featuring Swift spring upgrades. Designed for the 2015-2021 Subaru WRX / STI, it utilizes a mono-tube digressive piston design that provides superior damping response over a wide range of surfaces.

These coilovers offer 30 levels of damping adjustability, allowing users to fine-tune their suspension for both street and track use. The height is adjustable independently of spring preload, ensuring full suspension travel at any ride height. Swift springs offer improved performance and handling characteristics compared to standard spring options.

Installation requires standard automotive hand tools and basic suspension knowledge; it is recommended to have the vehicle aligned professionally after installation to account for geometry changes.

This coilover system is specifically engineered for the 2015-2021 Subaru WRX / STI chassis and is not compatible with other platforms.
