Why Choose the ST XTA Plus 3 Coilover Kit
The XTA Plus 3 is one of the best-value coilovers available for the F2X platform, using proven KW Automotive technology packaged with ST’s durable materials and accessible pricing. The three-way adjustability allows you to fine-tune compression for bumps and kerbs separately from body control, while the rebound adjuster lets you tailor how the car settles through corners.
The included camber-adjustable aluminium top mounts deliver the precision and alignment flexibility needed for modern performance tyres. The result is a suspension setup that feels significantly more responsive and confidence-inspiring than OEM, without stepping into full motorsport damping.
For M135i, M140i, M235i and M240i owners who want a serious fast-road and track-ready setup, the XTA Plus 3 is an exceptional upgrade.

Professional installation, alignment and corner balance are strongly recommended.
