Kaditcha was an automobile manufacturer in Australia. The company, formed by Queensland engineer Barry Lock, made open wheel and sports car racing cars, including cars for Formula 5000 and Australian Formula 2. The peak of Kaditcha's form was in the mid-1980s when Kaditcha sports cars dominated the Australian Sports Car Championship with one-two finishes occurring regularly from 1983.[1]
Kadticha's most famous race car is one that no longer bears its name. The Romano WE84 Cosworth raced by Bap Romano began its racing life as the Kaditcha K583.[2] Romano used the WE84 (re-engineered by former Williams and Tyrrell Formula One mechanic Wayne Eckersley) to easily win the 1984 Australian Sports Car Championship.
Lock was later involved in the Giocattolo project and the Infiniti sports racing cars.
