Tuhia he haere tonu mō tēnei wāhanga - I whakataetae ngā motokā Brabham i te Indianapolis 500 mai i te waenganui o ngā tau 1960 ki te tīmatanga o ngā tau 1970. Whai muri i te kaupapa i paopao i te tau 1962, i tonoa a MRD i te tau 1964 ki te hanga i tetahi miihini IndyCar e akiakihia ana e te miihini Offenhauser Amerika. Ko te BT12 chassis i puta mai i a Jack Brabham hei "Zink-Urschel Trackburner" i te huihuinga 1964
ka reti me te raru o te ipu wahie. I whakauruhia ano te motuka i te tau 1966, ka eke ki te tuatoru mo Jim McElreath. Mai i te 1968 ki te 1970, ka hoki mai a Brabham ki Indianapolis, i te tuatahi me te putanga 4.2-rauna o te Repco V8 i whakamahia e te tiima i roto i te Whakatakotoranga Kotahi <unk> i oti ai a Peter Revson i te tuarima i te 1969 <unk> i mua i te hokinga ki te miihini Offenhauser mo te tau 1970. I uru ano te huinga Brabham-Offenhauser i te tau 1971 na J.C. Agajanian, i mutu te tuarima i nga ringa o Bill Vukovich II. Ahakoa kaore he motuka Brabham i wikitoria i Indianapolis, i wikitoria a McElreath i nga whakataetae e wha o te United States Automobile Club (USAC) i te 1965 me te 1966 i te BT12. Ko te "Dean Van Lines Special" i wikitoria ai a Mario Andretti i te 1965 USAC toa toa a motu he kape tika o tenei motuka, i hangaia me te whakaaetanga mai i a Brabham e te rangatira o te roopu o Andretti a Clint Brawner. I riro i a Revson te wikitoria whakamutunga a Brabham i te whakataetae USAC i roto i te BT25 i te 1969, ma te whakamahi i te miihini Repco.
