WeiRC RC Parts & Upgrades for Mi9

WeiRC specialises in precision steel components that let Mi9 drivers fine-tune handling and durability. Popular options include the WeiRC Steel Chassis 1.2mm for Mi9, designed to alter flex characteristics while adding low-down mass for a planted, consistent feel, and the WeiRC Steel Screw Set for Mi9 Steel Chassis, providing complementary hardware specified to suit the chassis.

Whether you are chasing lap-time consistency or looking to change the car’s balance for different track conditions, these WeiRC parts offer a focused upgrade path. The 1.2mm steel chassis gives a distinct on-track response compared with lighter materials, while the matching screw set helps maintain fit, longevity and a tidy build. For best results, pair the chassis with the dedicated screw set and review product notes for compatibility and setup guidance specific to your Mi9.
