Drivers seeking a controllable, repeatable front end will benefit from the XRAY 302181-M X4 Medium Carbon-Fiber Fusion Front Lower Arm Left. The medium-hardness profile provides a measured amount of flex without compromising stability.
The arm uses a carbon fibre centre plate encased in a composite outer layer so the two materials act as one unit. The carbon core sets the main stiffness while the composite helps fine-tune flex and rebound for predictable steering feel.
Medium hardness works well on sealed surfaces, offering a mix of traction and responsiveness. Compared with harder arms these generally increase grip in warm conditions and make the car easier to place through fast sections.
Built for the XRAY X4 chassis, the left front arm fits standard mounting points and retains factory geometry for a straightforward swap.
