AST Suspension BMW X3M (F97) / X4M (F98) Adjustable Lowering Springs

AST Suspension Adjustable Lowering Springs – BMW X3M (F97) / X4M (F98)

Performance Ride Height Control for the Modern M SUV

Take total control of your ride height and stance with the AST Suspension Adjustable Lowering Springs (ALS) for the BMW X3M (F97) and X4M (F98). Designed for enthusiasts who want coilover-level adjustability without giving up their factory dampers or electronic control systems, this kit brings you the best of both worlds—form and function.

Engineered in the Netherlands and trusted worldwide, the AST ALS system allows you to fine-tune your ride height with threaded collars and precision-crafted spring perches. Whether you’re dialing in a daily-driver drop or prepping for a spirited weekend drive, this kit lets you adjust your suspension without compromise.

🔧 Tech Highlights:

• Adjustable Ride Height: Drop the front 0–40mm and the rear 0–35mm, tailored to your exact setup.

• Direct Fitment: No cutting, no mods. Built specifically for the BMW F97 X3M and F98 X4M, including Competition models.

• EDC-Compatible: Retains full factory Electronic Dampening Control functionality.

• High-Tensile Springs: Built to last with cold-wound, shot-peened materials that hold up under pressure.

• Threaded Adjusters: Precision-machined for smooth height adjustments and long-term reliability.

💯 Why It Matters:

OEM springs are a compromise. With AST’s height adjustable spring kit, you're not just lowering your X3M or X4M—you’re unlocking tighter handling, reduced body roll, and a more aggressive stance, without killing ride quality or tech features.

This isn’t a cut corner solution. It’s a smarter, cleaner, more modular approach to dialing in your suspension.
