TEIN Street Advance Z (SAZ) Coilover Kit for BMW 5 Series F10 520i Saloon 2011-2016 – Height Adjustable Performance Suspension, 16-Way Damping, Fast-Road Lowering Shocks & Springs Upgrade

Transform your BMW F10 520i with adjustable street and fast-road suspension

Give your 2011 to 2016 BMW 5 Series saloon the stance, control and comfort it deserves with this TEIN adjustable suspension kit. Engineered for everyday driving and spirited B-road blasts, it delivers precise ride-height control and a wide damping range so you can dial in plush comfort for the commute or firm it up for sharper turn-in and reduced body roll at the twist of a knob.

Why this upgrade stands out

• Height adjustable suspension for a purposeful drop and confident handling without sacrificing daily usability.
• 16-stage click adjustability with a needle-type adjuster for a noticeable, more than 200% change between softest and firmest settings.
• Short-body design helps maintain usable stroke at lowered ride heights for better control over bumps and undulations.
• Corrosion-resistant threaded sleeves and a powder coated body for long-lasting performance through UK weather.
• Twin-tube construction with high-performance damper oil for consistent, street-focused refinement.
• Direct-fit, bolt-on replacement that reuses the original upper mounts for a factory-like installation.
