If you’re looking to achieve greater front end feel and grip from your F2X M135i, M235i, M140i or M240i (as well as other F2X variants, and F3X 3/4 Series) then converting to F8X M4 front control arms is a popular option.

However, the tension strut bushings on the F8X have a different thickness compared to the F2X/F3X, and so conversion spacers must be used and must be in an offset for the correct geometry.

Our Control Arm Conversion Spacer Sets are CNC-machined in the UK from premium grade aluminium. Priced per vehicle set.
