Why Choose the ST XTA Plus 3 Coilover Kit
The XTA Plus 3 delivers KW-influenced damping performance at a more accessible price point, making it one of the strongest value-for-money coilover options for the E9X M3. Three-way adjustment allows you to fine-tune how the car behaves over bumps (high-speed compression), through weight transfer (low-speed compression), and as it settles mid-corner (rebound).
The supplied camber-adjustable top mounts improve initial steering bite and tyre contact patch control — essential for fast-road and track setups. With durable construction and a proven monotube design, the XTA Plus 3 offers consistency even during long, high-heat driving sessions.
For S65 owners wanting a serious handling upgrade that sits between KW V3 and Clubsport systems, the XTA Plus 3 is an outstanding choice.
Installing / Notes
-
Professional installation, alignment and corner balancing are highly recommended
-

-
