Im going to do my best to do a run through the first to last OPTIMA models. Feel free to correct me if I stuff this one up guys.....
Optima
Turbo Optima
Optima Pro
Optima Mid
Turbo Optima Mid
Optima Mid SE
Optima Mid Custom
Optima Mid Custom Special.
Sure Ive left out the Javelin and possibly a couple others but you get the idea. Ive owned a couple of OPTIMA MID CUSTOM SPECIAL cars and they came with the very rare (and expensive) carbon fibre saddle pack chassis kit. Im certain its the same wheelbase as the MID CUSTOM and MID CUSTOM SPECIAL but I think Kyosho released this kit to help racers convert the shorter wheelbase Optima Mid's into the longer wheelbase car. The kit included belts, chassis plates and lexan cover Im sure.
Anyway these were the two cars I owned.
