The XRAY 372132 X1 Graphite Upper Suspension Arm gives owners of older X Series models a straightforward route to improved response. Built from 2.5mm graphite, the part reduces weight while providing tuned flex characteristics that help with steering control. It is aimed at restorations and incremental upgrades for ageing X1 cars.
Graphite is prized for its low weight and predictable flex compared with heavier materials. The 2.5mm section used here balances rigidity and compliance so the arm absorbs track irregularities without making the chassis feel vague.
This component is made to slot into existing upper arm mounts on early X Series models, requiring no chassis modification in most cases. It is a practical swap-in for maintaining original geometry while improving part life and handling.
