Product Details
These Triple S lowering springs fit the 2015-2020 Subaru WRX STI.
Triple S Lowering Springs for the Subaru WRX STI lower the center of gravity for sharper turn-in and less body roll while keeping daily-driver comfort. These progressive-rate springs for the Subaru WRX STI give an approximate -15mm front and -18mm rear drop. They are a direct replacement for the factory coils and bolt in without cutting, welding, or other modifications.
Every Triple S application is matched to the stroke of the factory dampers. That means the factory shocks stay. The result is a mild, street-friendly drop that keeps ride quality.
Triple S springs are cold-forged from SAE9254 silicon-chromium alloy by Yang Min Enterprise, an OEM coil-spring manufacturer with over 50 years of experience and ISO 9001, IATF 16949, and ISO 14001 certifications. Cold forging gives higher stress tolerance and tighter rate consistency than hot-forged springs. A durable blue powder-coat finish resists chips and corrosion, and every set is backed by a 1-year manufacturer defect warranty.
Kit includes one pair of front springs and one pair of rear springs (4 total). Silencer rubbers are included where applicable.
