ST XA Adjustable Suspension for BMW 3 Series E90 E92 xDrive AWD 2006 to 2013 - PN 18220048

Give your xDrive BMW 3 Series a serious upgrade in grip, control and stance. The ST XA adjustable suspension package delivers precise ride-height tuning and rebound control so you can dial in comfort for the daily commute, then sharpen things up for fast B-road driving. Developed with KW Automotive know-how, this set is the sweet spot for real-world performance and reliability on UK roads.

If you are chasing tighter steering response, flatter cornering and a purposeful drop without sacrificing everyday usability, this is the solution. We have fitted and driven on ST XA at MJ Modifications and our customers consistently praise the improved confidence, reduced body movement and the ability to fine-tune the damping to match wheels, tyres and driving style.

Why it belongs on your xDrive BMW

• Ride-height tuning via threaded bodies for a clean, even drop and proper wheel fitment.
• Rebound adjustment at the top of the piston rod to switch from comfortable to sporty in seconds.
• Sharper handling with reduced roll, improved stability and quicker turn-in compared with factory suspension.
• Durable build using galvanised steel struts and twin-tube dampers for long-term corrosion resistance and consistent performance.
• KW engineered valving for confident road manners and dependable damping control in all weather.

Lowering range

• Front: 15 to 45 mm drop (approx. 0.6 to 1.8 inches)
