The XRAY 373027 Aluminum Rear Bulkhead - Left is a purpose machined upgrade for X1'20 cars, made from Swiss 7075 T6 aluminium for reliable stiffness and consistent mating with surrounding components. The black surface finish helps protect the material and keeps installation neat.
Designed to interface with the independent wing mount, this bulkhead moves the differential 0.5mm lower to broaden ride height options and achieve finer balance during setup. Reinforced areas reduce susceptibility to bending during impacts.
Excess material is removed where safe to lower weight without compromising strength, helping the car sit lower and respond better through direction changes and corner entry.
Ride height tuning is simplified by inserting shims between the bulkhead and upper clamp, permitting 0.25mm increments that let you dial in corner behaviour more accurately than 0.5mm steps.
