KW HAS Adjustable Lowering Spring Kit for BMW M3 E90 E92 E93 (E9X) & BMW 1M E82 | EDC/Adaptive Damping Compatible Coilover Alternative | Threaded Sleeve Ride Height/Drop Springs | P/N 25320057, 25320063

Adjustable Ride-Height Spring Set for BMW E9X M3 and E82 1M - EDC friendly - KW HAS - PNs 25320057 and 25320063

Transform the way your BMW looks and drives with the KW HAS adjustable spring conversion. This premium suspension upgrade lets you fine tune the drop for the perfect stance while keeping your factory shock absorbers and BMW adaptive damping fully operational. Ideal for owners who want coilover-like height control with OEM refinement, road comfort and track-ready precision.

Key advantages

• Dial-in ride height via threaded collars for exact arch-to-tyre fitment on your wheel and tyre setup
• Works seamlessly with BMW EDC adaptive dampers so you keep your driving modes and everyday usability
• Chassis-specific rates deliver sharper turn-in, reduced body roll and improved mid-corner stability
• High-quality chrome-silicon spring steel with a durable weather-resistant finish for long service life
• OE-style integration with model-specific bump stops and dust protection included
• Great alternative to a full coilover kit if you want adjustable lowering without replacing your dampers

Set the drop for daily driving, track days or show stance, then tweak it again any time you change wheels or tyres. Expect confident grip, flatter cornering and a lower, cleaner aesthetic that still rides well on British roads.
