Front Axle Geometry Upgrade for BMW M135i, M235i, M140i, M240i

Unlock sharper steering, extra front-end bite and a more planted stance with this OEM-style retrofit using M3/M4-spec arms. Designed for the F2x platform, this front suspension package adds approximately +1° of negative camber on the nose and gently increases front track width for improved cornering confidence on fast road and track days.

If you are chasing quicker turn-in, reduced push in tight bends and a more stable car under braking, this is the proven, plug-in solution enthusiasts choose for their 1 Series and 2 Series performance builds.

Why enthusiasts choose this setup

  • Approx. +1° front negative camber for stronger front grip and quicker steering response
  • Slightly wider front stance for improved stability and road presence
  • OEM-style fitment with no fabrication required
  • Includes spacers and headlight levelling sensor bracket for a tidy, factory-like install
  • Ideal for fast road, canyon/B-road driving and track day use

What is included

  • Pair of lower wishbones (left and right)
  • Pair of tension struts / thrust arms (left and right)
  • Spacer set
  • Headlight levelling sensor bracket

Real-world results

We run this upgrade ourselves and our customers consistently report noticeably cleaner turn-in, better mid-corner stability and more confidence when leaning on the front tyres. It is a superb OEM+ handling mod that compliments performance tyres, springs, dampers and wider wheels.
