This RC-grade graphite rear hub is produced for MR-4TCSD layouts and provides a fixed 0.5deg rear toe bias. It is intended as a direct replacement or upgrade in MR-4TCSD-compatible drift packages, concentrating on chassis balance and rear suspension tuning rather than introducing extra features.
Installation notes: the hub mounts at the standard rear hub position on MR-4TCSD designs and uses the original hub assembly mounting points and fasteners. Confirm fitment before final assembly, check wheel hex engagement and bearing seating, and torque fasteners to your chassis manufacturer's recommended values.
Tuning role: a fixed 0.5deg rear toe bias alters rear-end behavior by affecting turn-in stability and slip angle during drift sections. The graphite construction reduces compliance compared with softer materials, producing a crisper rear response when you adjust other rear geometry settings.
