The JAZRIDER JR-OT11 carbon rear shock stay is a precision upgrade for the Kyosho Optima 2016, providing a firmer, lighter mounting platform for the rear shocks. It supports the Optima 4WD setup and helps the car hold line through technical sections.
Carbon fiber parts reduce mass while increasing rigidity at key points. Switching to this carbon stay cuts unnecessary weight and resists deflection, improving steering consistency and rear traction response.
This shock stay is engineered to match the Kyosho Optima 2016 mounting pattern and fits using standard hardware. The installation is straightforward and returns quick improvements without chassis modification.
