RCG Racing Tracer / MT-One 金屬後輪軸、插銷與鎖緊螺母 M4 (升級件)

Swapped these onto my MT-One and the fit is spot on, the lock nut threads are clean so no stripping when I torqued them down. Way sturdier than the stock pins, and knowing they drop into the FTX Tracer too makes them a no-brainer.

These M4 shafts are a solid upgrade—the metal feels noticeably more rigid than the stock plastic bits, and the lock nuts threaded on cleanly without any fuss. Swapped them into my Tracer in about ten minutes and the rear end tracks straight with zero wobble now.

They work as advertised for the MT-One, and the M4 lock nuts thread on cleanly, but the pins felt a bit softer than I expected for a "hop-up" part. Fine for casual bashing, though I wouldn't push them too hard.
