I taua wa ano, i whakatata atu a DuPont ki te kamupene Hinchman mo te whakaputa i nga kakahu whakataetae Nomex. I Indianapolis 500 o taua tau, i mau te taraiwa a Mel Kenyon i te koti ahi Nomex i hangaia e Hinchman.

I tukuna e te kamupene Simpson Simpson Performance Products te koti whakataetae Nomex tuatahi, i huaina ko te "Heat Shield Firesuit", i te tau 1967. I mau i ngā kākahu e 30 o te 33 o ngā kaiwhakataetae i te whakataetae
Ko te 1967 Indianapolis 500.
