KW Height Adjustable Spring Kit (H.A.S) – BMW M3 E90 E92 & 1M (2008–2013)

Give your BMW M3 or 1 Series M a sportier, more planted stance without losing the refinement of the factory suspension. The KW Height Adjustable Spring Kit (H.A.S) allows you to fine-tune your ride height even after installation, while keeping your factory electronic dampers and driving modes fully functional.

Key Features

• Adjustable Ride Height After Installation — Easily raise or lower your car with millimeter precision whenever you want
• Works With Factory Electronic Suspension — Keeps your EDC (Electronic Damper Control) fully operational. Switch between Comfort and Sport modes with the push of a button — no need to get out and twist dials
• No Coding Required — Avoid the hassle of coding out suspension errors that often comes with full coilover installations on cars with electronic dampers
• Vehicle-Specific Spring Rates — High-quality chrome-silicon steel springs developed and tested on the Nürburgring Nordschleife and KW’s 7-post driving dynamics rig
• Includes Bump Stops & Dust Protection — Protects your factory dampers from road debris and wear
• Improved Handling & Response — Lowers the center of gravity for sharper steering and more confident cornering while maintaining daily drivability
• Limited Lifetime Warranty — Unlimited mileage

Why Choose KW H.A.S?

Unlike traditional lowering springs or full coilovers, the KW H.A.S kit gives you the flexibility to adjust your ride height on the fly while preserving the factory electronic suspension system. This means you can keep using your Comfort and Sport modes with a simple button press, instead of manually adjusting dampers every time you want to change the character of the car.

KW engineers develop vehicle-specific spring rates and parameters through extensive testing on the Nürburgring, ensuring the springs work in harmony with the factory dampers for a balanced, sporty, and comfortable driving experience.
