Arm Bush BMW X1-Series (F48/F49)

PFF5-1301GFX Front Arm Front Bush Fixed Offset uses CNC-machined Aluminium outer shells with a fixed offset bore to ensure wheel geometry is maintained during kerb strikes and with the extreme lateral forces generated by slick tyres and circuit racing. This is paired with a Black 95Adurometer bush with a knurled bore, for increased stiffness (+60%) and durability over the OE rubber bush, resulting in minimal wishbone stiction and significantly reduced deflection.Increasing negative camber by 0.75, this bush achieves reliable, grip-focused wheel geometry, tested and approved by the Mini Challenge; and perfectly complements our PFF5-1302BLK /PFF5-1302GBLK Front Arm Rear Bushfor those serious track and race car builds; especially when combined with adjustable top mounts.
