Millway Motorsport Street Front Control Arm Bushings (F2X/F3X 1/2/3/4 Series)

Transform steering feel and front end precision on your BMW F-series with Millway Motorsport’s road-focused sealed spherical bearings for the lower front arms. This premium wishbone bush replacement sharpens turn-in, boosts stability under braking and delivers repeatable alignment on spirited drives and track days.

Built for owners chasing a serious handling upgrade without excess noise or harshness, these enclosed monoball units replace the soft OE rubber bush in the tension strut, cutting compliance and keeping geometry true lap after lap.

Why enthusiasts choose this upgrade

• Sharper steering response and tighter turn-in
• Reduced front axle deflection for consistent camber and toe
• Improved braking stability and mid-corner confidence
• Road friendly refinement thanks to a sealed spherical bearing
• Ideal for fast road use and track day setups

Engineering that lasts

• Precision machined from solid aluminium for strength and accuracy
• High quality sealed uniball for durability in UK weather
• Stainless steel spacers and hardware to resist corrosion
• Straightforward installation with no drama
