Kyosho Optima Mid 30643 Returns as a 1987 Worlds Prototype Reimagined
In off-road racing history, the Optima Mid stands out. The original prototype made a notable impact at the 1987 IFMAR 4WD World Championships by getting multiple cars into the A-Main. For Kyosho's 60th Anniversary the 30643 brings that Worlds-spec prototype back with modern engineering while staying true to its roots.
Mid-Motor Carbon Layout and Balance
The Optima Mid introduced a mid-mounted motor and a double-deck layout that delivered a balance and stiffness uncommon at the time. This anniversary kit recreates that architecture with a carbon main chassis and carbon upper deck for a tuned mix of rigidity and controlled flex suited to current brushless setups.
Anniversary Finishes and Period Styling
This limited run blends historic visuals with updated materials. Gold hardware is replaced by a gunmetal finish, the Optima Pro body is remoulded for the mid-chassis layout and a large rear polycarbonate wing is included. The peppermint green Ultima-style wheels reproduce Akira Kogawa's classic look.
Track-Ready Components Included
The kit comes with items many racers add after buying a car: ball diffs front and rear, titanium-coated shock shafts with carbon towers, universal swing shafts, HD mounts and an easy turnbuckle setup for camber and toe. The 7075 duralumin main gear shaft reduces rotating mass and suits modern LiPo and brushless powertrains.
Build, Tweak and Run
This is a true kit for hobbyists. You assemble from the chassis up, fit your radio, servo, ESC, motor and battery, and then tune. It works as a competitive vintage-inspired racer or as a display piece that celebrates Kyosho engineering.
