The original two chassis were raced by Brabham and Rindt in the season opening 1968 South African Grand Prix, but with the BT26 ready in time for the next race, these two chassis were sold to local teams and left in South Africa, with Sam Tingle and Basil van Rooyen finishing third and fourth in that year's South African Formula One Championship. Sam Tingle later took part in the 1969 South African Grand Prix, the last World Championship Formula One event for a standard BT24, and continued to race his chassis with some success in local events as late as January 1970, while van Rooyen's car was also raced at various times by Gordon Henderson and Ivor Robertson.
