XTA plus 3 triple‑adjustable coilover suspension for BMW F2x and F3x

Unlock razor sharp handling, confidence on British B-roads and dialled-in stance with the XTA plus 3 performance suspension system. Built with KW engineering and race-bred hardware, this premium spring and damper package gives you independent control of rebound, low-speed compression and high-speed compression, plus ride height and camber via aluminium top mounts. Ideal for spirited road use, track days and daily driving comfort, it fits a wide range of rear-wheel-drive BMW 1 Series, 2 Series, 3 Series and 4 Series F-chassis models including 125i, 225d, 330i, 335i, 340i, 435i, 440i, M135i, M140i, M235i and M240i.

What you get with XTA plus 3

  • Three-way damping control for total chassis tuning: 24 clicks low-speed compression, 24 clicks high-speed compression, 18 clicks rebound.
  • Camber-adjustable aluminium uniball top mounts where applicable for sharper turn-in and maximum tyre contact patch.
  • KW-developed twin-tube internals with low-friction sealing and outstanding corrosion protection for year-round reliability.
  • Threaded bodies front and rear to fine-tune ride height for road, track or stance.
  • Race spring system, adjustable perches, bump stops and dust boots included as a complete kit.
  • Supplied with a parts approval certificate for road use where applicable.

Real-world gains you can feel

Separate control of high and low-speed compression lets you calm body roll and pitch without making the ride harsh over bumps. Rebound adjustment sets support and ride quality, so you can add stability for fast corners or soften for daily comfort. The result is precise steering, stronger traction and a planted rear end, with the flexibility to switch between road-friendly and track-focused settings in minutes.

Built to perform and last

Each galvanised strut is treated for durability and sealed to keep performance consistent in all weather. The mono-block guide and seal package minimises friction for repeatable adjustment. Camber plates use motorsport-grade uniball bearings to sharpen feedback and maximise front-end grip.

Lowering and adjustment

Continuous thread height adjustment allows you to set the exact ride height you want by moving the spring perches up or down even after installation. Note that the achievable lowering range depends on the specific F2x or F3x variant and factory equipment. If you would like guidance on target heights for road, fast-road or track use, our team is happy to help.
