ST Suspension XTA Plus 3 Coilover Kit BMW E90 E92 M3
Product Description
The ST XTA Plus 3 Coilover Kit for the BMW E90, E92 and E93 M3 is the highest-spec suspension upgrade in the ST range, designed for S65-powered M3 owners who want serious chassis control, detailed damping adjustment and improved alignment flexibility. Developed in partnership with KW Automotive, it offers KW-derived suspension performance in a more accessible package.
Unlike simpler coilover systems, the XTA Plus 3 features full 3-way damping adjustment, allowing independent control of rebound, low-speed compression and high-speed compression. This gives drivers the ability to fine-tune how the car behaves under braking, through weight transfer, over bumps and kerbs, and as it settles mid-corner.
The kit includes aluminium camber-adjustable top mounts, helping improve front-end grip, steering response and tyre contact patch control. This makes it especially well suited to fast-road and track-day setups, particularly for cars running semi-slick tyres, aggressive alignment or increased performance.
Built around a monotube damper design, the XTA Plus 3 is engineered to deliver consistent performance under heat, making it suitable for longer, more demanding driving sessions. Progressive springs help retain balanced road behaviour, while front and rear height adjustment allows the stance and centre of gravity to be set within the TÜV-certified lowering range.
This kit is designed exclusively for BMW E90 M3 Saloon, BMW E92 M3 Coupé and BMW E93 M3 Convertible models with the 4.0 V8 S65 engine. Motorsport-style top mounts may increase noise, vibration and harshness compared with OEM mounts.
Professional installation, alignment and corner balancing are highly recommended to get the best from the system.
