ST XTA Plus 3 Coilover Kit (Damping Adjustable With Top Mounts) for BMW F2X 35i 40i
Product Description
The ST XTA Plus 3 Coilover Kit is a top-tier suspension upgrade for BMW F2X M Performance models, including the BMW F20/F21 M135i, F20/F21 M140i, F22/F23 M235i and F22/F23 M240i. Designed for drivers who want sharper chassis response, full damping control and improved alignment flexibility, it offers a serious fast-road and track-ready setup without stepping into full motorsport suspension.
Developed in partnership with KW Automotive, 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 kerbs and bumps, and as it settles mid-corner.
The kit includes aluminium camber-adjustable top mounts, helping improve steering precision, front-end grip and tyre contact patch control. This is especially useful for cars running high-grip tyres, increased power, lower ride heights or track-focused alignment settings.
Built around a monotube damper design, the XTA Plus 3 is engineered to deliver consistent performance under sustained use. Progressive sport springs help retain balanced fast-road behaviour, while front and rear height adjustment allows the stance, centre of gravity and handling balance to be set within the TÜV-certified lowering range.
This kit is designed for N55 and B58-powered BMW F2X M Performance models. Motorsport-style top mounts may increase noise, vibration and harshness slightly compared with OEM rubber mounts.
Professional installation, alignment and corner balancing are strongly recommended to get the best from the system.
