The Optima Mid prototype caused a stir at the 1987 IFMAR 4WD World Championships when several cars reached the A-Main. Kyosho celebrates that engineering with the 30643 anniversary kit, blending the original concept with modern component choices for durability and setup options.
The mid-mounted motor and double-deck arrangement were the car's signature traits, delivering a balanced centre. The anniversary model reproduces this layout using a carbon main chassis and carbon upper deck to deliver current levels of stiffness and mount reliability.
The special run keeps the 1987 livery but switches hardware to a gunmetal finish for a contemporary race look. The Optima Pro body is adapted for the mid-chassis layout and a large rear poly wing is fitted. Peppermint green Ultima-style wheels echo the original styling cues.
What would often be aftermarket parts are included here: ball diffs front and rear, titanium-coated shock rods paired with carbon towers, universal swing shafts, HD mounting points and a turnbuckle system for fast camber and toe changes. The 7075 duralumin main gear shaft helps improve throttle response under modern power loads.
This is a kit meant for assembly and setup. You will install electronics then tune springs, damping and alignment. Whether used on the track or displayed, the 30643 bridges classic lines with usable modern features.
The Optima Mid 30643 is ideal for anyone who wants a period-correct feel with modern parts that make setup and maintenance straightforward for competitive running or showroom display.
