Height Adjustable Suspension for BMW 3 Series E9x 2005 to 2012
Transform the way your BMW drives and looks with this premium height adjustable suspension system engineered by the team behind KW Automotive. Perfect for drivers who want precision ride-height control, sharper handling and a purposeful stance on E90 saloon, E91 Touring and E93 convertible models.
Why enthusiasts choose this upgrade
- Precision height adjustment for the perfect road stance and cornering balance
- Sharper turn-in and reduced body movement for confident fast-road driving
- Durable galvanised bodies with additional coating for long-term corrosion resistance
- Twin-tube damper technology with chrome-plated piston rods for smooth, consistent performance
- Composite adjuster collar that makes ride-height tweaks quick and easy
- Developed and produced by KW’s manufacturing experts for OE-grade reliability
Lowering range and axle loads
- Front drop: 30 to 60 mm
- Rear drop: 25 to 55 mm
- Maximum permitted axle load: Front 1090 kg, Rear 1135 kg
This suspension kit gives you the flexibility to dial in a tasteful drop for daily use or a more aggressive ride height for a show-ready look, all while improving stability and road feel. The threaded design lets you fine-tune the setup to your wheel and tyre combination for even arch gap and a level, controlled stance.
Real-world results
We have installed this setup on customer cars and our own builds, and the feedback is consistently positive. Expect a tighter, more connected feel on B-roads, better mid-corner composure and a confident ride without the harshness you get from cheap alternatives.
Fitment and compatibility
Designed for BMW 3 Series E9x models from 2005 to 2012, including E90, E91 and E93 variants within the stated axle load limits. If you are unsure about suitability for your specific model or engine variant, contact us and we will be happy to help.
