The COBB Sway Bar Package is a complete front and rear sway bar upgrade engineered specifically for the 2015–2021 Subaru STI, including the limited-edition 2018 Type RA and 2019 S209 variants. Designed to dramatically reduce body roll and sharpen cornering response, this package delivers a more connected, confidence-inspiring driving experience whether you're attacking an autocross course or carving mountain roads. COBB's precision-engineered sway bars work in harmony with the OEM suspension geometry for a true bolt-on performance upgrade.

Key Features & Benefits

• Complete Front & Rear Package – Everything needed to upgrade both sway bars in one kit, eliminating the guesswork of component matching.
• Significantly Reduced Body Roll – Stiffer bar rates keep the chassis flatter through corners, improving lateral grip and driver confidence.
• Improved Steering Response – Reduced chassis flex translates to a more direct, communicative steering feel and faster turn-in.
• High-Strength Construction – Manufactured from premium steel with precision tolerances for durability under repeated high-stress driving conditions.
• Includes Upgraded End Links – Matched end links ensure proper geometry and eliminate the weak link of the OEM end link design.
• Direct OEM Replacement Fitment – Engineered to bolt directly onto the STI's factory suspension mounting points — no cutting, drilling, or fabrication required.
• Compatible with STI Special Editions – Specifically validated for the 2018 Type RA and 2019 S209, which feature unique suspension tuning from the factory.
• COBB Quality & Engineering Pedigree – Developed by one of the most trusted names in Subaru performance, backed by extensive real-world testing.
