KW HAS Height Adjustable Lowering Springs Kit (Coilover-Style Spring Sleeves) for BMW 1M 1 Series M Coupe E82 2011+ | Ride Height Adjustable Suspension Drop Kit | Works with OE Dampers | Front 10-30mm / Rear 0-20mm

KW Adjustable Ride Height Spring Set for BMW 1 Series M Coupe E82 2011 on

Give your BMW 1M the stance and handling it deserves. This KW adjustable spring set, often referred to as KW HAS, replaces the standard springs with height-adjustable sleeves and performance springs so you can dial in the perfect drop while keeping your original shock absorbers. The result is OEM-plus comfort with sharper response, improved body control and a road presence that looks right with factory wheels or aftermarket setups.

We have installed this kit at MJ Modifications on multiple 1M builds and customer feedback has been outstanding. Owners report crisper turn in, more confidence on fast A-roads, excellent ride quality for daily use and the flexibility to fine tune ride height to suit tyre sizes and alignment targets. If you are searching for a BMW 1M suspension upgrade that keeps factory dampers but adds precise height adjustability, this is the go-to solution.
