The JAZRIDER JR-OT03 aluminium bumper support is a purpose-built front brace for the Kyosho Optima 2016 chassis. It provides a robust contact point to reduce chassis flex at the nose while remaining lightweight and serviceable for regular use.
Aluminium offers predictable deformation characteristics and easy machining if minor fit tweaks are needed. The JR-OT03 is suitable for hobbyists who prefer durable, low-maintenance parts they can service trackside.
Fitting typically uses the Optima 4WD mounting pattern and common hand tools. Check alignment with body mounts during install and secure fasteners with thread locker where needed for fault-free running.
