Walker ran Willy T. Ribbs sporadically until 1994, but enjoyed his best success in the early seasons with Scott Goodyear. Goodyear came second to Al Unser, Jr. in the 1992 Indianapolis 500 by 0.043 seconds, the closest finish to date in the race's history, and later won the 1992 Michigan 500 for Walker over then-Penske newcomer Paul Tracy. Goodyear and Robby Gordon spent large amounts of time with Walker, with 1996 their last season. Gordon left to pursue a further NASCAR career with Goodyear in the new Indy Racing League. Walker hired Gil de Ferran, who came close to winning the 1997 title without winning a single race. He ran a second car for Naoki Hattori and Memo Gidley in 1999 but neither did well. Walker also ran a team in the Indy Racing League for Sarah Fisher in 2000 and 2001 with limited success.
