This carbon front shock stay is an aftermarket replacement for the KYOSHO Optima 2016 chassis, supplied as JR-OT10. It gives a rigid anchor for front shocks so tuners can refine geometry and damping without chassis-induced variation.
Use the stay when consistent shock top positioning is required for iterative setup, shock comparison, or when testing alternative spring and damper combinations on the Optima 2016. The part helps reduce variables caused by a more flexible stock stay.
Fitting is typical of 1/10-scale parts: remove the existing stay, inspect the mounting points, reuse or replace compatible hardware as necessary, and secure the new stay while ensuring the upper shock mounts are aligned. Basic hex drivers are adequate; recheck fastener torque after initial running.
