The FP-O-XCP037 uses a 4.0mm graphite plate in place of the original plastic mounting pad to improve stiffness where the body posts attach. Graphite balances low mass with stable dimensions so the post base sees less deformation during use.
The mount is contoured to match Xray X4'26 rear post locations and the rear cockpit cutout so the shell and rear wing retain factory alignment. Installation is intended to be a direct swap that preserves the original attachment geometry.
Serving as the structural anchor for rear body posts, the graphite plate delivers a consistent clamping surface that reduces post movement compared with flexible plastic mounts. This stabilisation helps during storage, transport and routine handling.
Regular racers, club tuners and collectors who want reliable, repeatable body positioning on X4'26 models will find this part useful as a practical replacement rather than a cosmetic tweak.
FP-O-XCP037 is a simple, effective replacement for X4'26 owners seeking a stiffer rear mounting surface and steadier shell alignment.
