Owners of the ST-R chassis looking to refine throttle feel can fit the Kyosho IFW167 lightweight spur gear. Its 50-tooth design focuses on reducing rotating inertia to help the drivetrain respond more quickly to inputs.
The Kyosho IFW167 spur is produced to offer a good mix of low weight and resistant material properties. This balance makes it suitable for repeated use while contributing to crisper acceleration characteristics on race day.
Built for ST-R compatibility, the Kyosho IFW167 swaps into common setups with minimal fuss. Ensure correct mesh, torque the mounting fasteners evenly, and trial the vehicle under light running to confirm smooth operation.
