ST Suspension XA Adjustable Coilover Kit for BMW 3 Series

Transform your BMW’s stance and road manners with the ST XA adjustable suspension kit for xDrive 3 Series F30 and 4 Series F32 models. Engineered alongside KW, this shock and spring package gives you precise control over ride height and rebound damping so you can dial in comfort for commuting or tighten things up for fast B-road blasts. Part number 1822000S.

This is the upgrade we trust on our own customer builds. The balance of control and compliance is superb, with sharper turn in, reduced body roll and confident traction on British roads, rain or shine. Set it up once for daily driving or fine-tune for weekend fun. Either way, the car feels more planted, more responsive and more enjoyable.

Key features

• Rebound adjustability using KW-developed internals lets you tailor the damping from supple to sporty via the on-car adjuster at the top of the piston rod.
• Ride height adjustability front and rear using continuously threaded spring perches for a precise stance and corner balance even after installation.
• Twin-tube damper construction with pressure-resistant housings for consistent performance over rough UK tarmac.
• Durable galvanised steel bodies with multiple seals designed to resist corrosion and cope with all-weather use.
• Delivers confident handling, flatter cornering and improved stability while retaining real-world comfort.

Lowering range

• Front: approx 30 to 61 mm
