This carbon rear shock stay is made for the KYOSHO Optima 2016 chassis and is identified by the JR-OT11 code. It operates as the mounting plate for rear shock absorbers and is intended to replace or upgrade the standard stay to alter mounting stiffness and shock geometry without changing the shock units themselves.
Install this stay when seeking a lighter, stiffer rear shock mount to explore handling adjustments; ensure the hole pattern aligns with the Optima 2016 chassis before installation and use proper fastening torque. The term carbon here denotes the material family commonly chosen for weight reduction and increased torsional stiffness in RC parts.
In setup, treat the stay as an element of the suspension system: modest shifts in mounting position or shock angle will affect rear traction and rebound. Conduct controlled test runs and adjust preload, shock length, and damping in small increments to find the preferred balance.
