Whakaotihia te rerenga e whai ake nei: I whakahaere a Walker i a Willy T. Ribbs tae noa ki te tau 1994, engari i pai tana angitu i nga wa o mua me Scott Goodyear. Ko Goodyear te tuarua i muri i a Al Unser, Jr. i te
1992 Indianapolis 500 e 0.043 hēkona, te mutunga tata ki te rā i roto i te hītori o te iwi, a muri riro te 1992 Michigan 500 mo Walker i runga i ka-Penske tauhou Paora Tracy. I whakapau kaha a Goodyear raua ko Robby Gordon i te wa nui me Walker, me te 1996 ko ta raua wa whakamutunga. I wehe a Gordon ki te whai i tetahi atu mahi NASCAR me Goodyear i roto i te Indy Racing League hou. I utua e Walker a Gil de Ferran, i tata ki te wikitoria i te taitara 1997 me te kore e wikitoria i tetahi whakataetae. I whakahaerehia e ia tetahi motuka tuarua mo Naoki Hattori me Memo Gidley i te tau 1999 engari kaore i pai te mahi. I whakahaerehia hoki e Walker tetahi roopu i te Indy Racing League mo Sarah Fisher i te 2000 me te 2001 me te angitu iti.
