This replacement upper arm pair is made for the Mini Spyder MT platform and is supplied as matching left and right front arms to align with the chassis orientation shown in the product name.
The arms act as suspension links between the steering knuckle and the chassis, influencing camber and roll behaviour while in motion. Fitment is intended for the Mini Spyder MT and the SER440001 chassis variant when using the original mounting points.
Installation notes: confirm that your knuckle ball studs and chassis mounting pin diameters match the arm's pattern, check full suspension travel for interference, and only finalise hardware torque after verifying free movement. Use these arms as part of stepwise tuning adjustments rather than a single drastic change to front-end behaviour.
