V3 Height-Adjustable Suspension Kit for BMW F31, F33, F34, F36

Take your F3x chassis to the next level with this premium height and damping adjustable shock and spring package. Perfect for BMW 3 Series Touring F31, 3 Series Gran Turismo F34, and BMW 4 Series F33 Cabriolet and F36 Gran Coupé, this two-way adjustable suspension gives you precise control over ride height, rebound and bump to deliver outstanding road manners and confidence on spirited drives and track days.

Built with corrosion-resistant stainless bodies and engineered for real-world use in all weather, this kit is the benchmark upgrade for owners who want sharper turn-in, more mid-corner grip and a composed ride without compromise. We run this setup on our own builds and customer cars, and the feedback is consistently excellent for balance, steering feel and stability.

Why this suspension upgrade stands out

• Stainless construction for long-term durability - resists corrosion for year-round use
• Continuous ride height adjustment - set the stance you want while keeping drivability
• Twin-tube damper design - supple on rough roads, composed when pressing on
• Proprietary valve technology - tune body control without needing different springs
• High-quality components and clear documentation for easy setup

How it transforms your BMW
