Under Spoiler Kit

The STI under spoiler is a factory-designed accessory intended to provide a more aggressive, ground-hugging aesthetic to the rocker panels of the Subaru BRZ. By extending the vehicle's lines, this side spoiler kit creates a lower profile look that complements the aerodynamic design of the BRZ platform. This complete kit includes both the left and right side under spoilers, providing a balanced visual upgrade. It also comes with the required rocker moldings and a dedicated hardware kit to ensure a secure, factory-standard fitment. Each piece is finished with the authentic STI logo to clearly signal its performance-oriented lineage. This is a special-order, non-refundable item. Installation involves replacing existing trim sections with these components. Please contact your local Subaru retailer to confirm fitment for your specific model year and trim level before purchasing.
