Whakakiia te rerenga e whai ake nei: Mo te tau 1951, i tino piki ake a Mutual i ana utu whakatairanga, a ko tana kaitautoko matua, Perfect Circle Piston Rings, i tangohia tana tautoko. I te mutunga ka whakatau a Mutual ki te whakamutu i te huihuinga, a, i puta mai mo tetahi wa kaore e tukuna te whakataetae 1951 i runga i te reo irirangi. I te tīmatanga o Mei o
1951, I whakatutukihia e te perehitini o Speedway a Wilbur Shaw he kirimana whakamutunga mo te WIBC ki te hipoki i te whakataetae, me Sid Collins hei kaikawe. I whai te whakatakotoranga a WIBC i a Mutual, me te purongo ora i te tiimata, te mutunga, me nga whakahou auau puta noa i te whakataetae. I whakaratohia e WIBC tana kapinga ki te 25 atu o nga hononga Mutual.
