 He is the son of open wheel driver Jerry Unser, cousin of Al Unser, Jr. and Robby Unser, nephew of Al Unser and Bobby Unser, and first cousin once removed of Alfred Unser.

 He made 5 starts in CART in 1993 and 1994 with a best result of 15th.
 He joined the Indy Racing League in its inaugural 1996 season but had a transmission failure during the pace lap of what would've been his first Indianapolis 500 and was not credited with a race start.
 In 1997 he made his first start in the Indy 500 starting in the 35th position after league and speedway owner Tony George added his and Lyn St. James' car to the field because slower cars than theirs were guaranteed starting positions because of prior races.
 He went on to finish 18th, his best "500" result in 5 starts.
 Unser drove the majority of his IRL races for Hemelgarn Racing and in his 14 career IRL starts he had a best finish of 9th in his very first series start in 1996 at Phoenix International Raceway.
 His last major open wheel race was the 2000 Indy 500.

Mark Dismore (born October 12, 1956 in Greenfield, Indiana) is a former driver in the Indy Racing League and the 1990 Toyota Pacific champion as well as the winner of the 1993 24 Hours of Daytona with Dan Gurney's All American Racers in a Toyota GTP car with co-drivers Rocky Moran and P. J. Jones.
 He made 3 CART starts in 1991 but was badly injured in a practice crash for the Indianapolis 500, when his car veered sharply towards the entrance of pit road at the exit of Turn 4 and back-ended the fence, only to careen across the pit lane and smash virtually head on at sizeable speed against the edge of pit wall; this second impact tore off the front of the car leaving Mark's legs exposed.
 Amongst the injuries he suffered, the most severe was a broken neck.
 He was largely out of open wheel racing until the 1996 Indy 500 where he drove for Team Menard though he did try to qualify in the 1992 Indianapolis 500 for Concept Motorsports in an outdated Lola/Buick.
 In 1997 he drove a second car at the Indy 500 for Kelley Racing and would become a full-time fixture there until the 2001 season.
 He returned to Menard for a partial season in 2002.
 Dismore has a single IRL win coming in the fall 1999 Texas Motor Speedway race and also finished a career-best third in points that season.
 Among his 62 career IRL starts he won four poles.

Phil Caliva (born January 1, 1945 in Palermo, Sicily) is an Italian-born American racing driver who competed in the CART Championship Car series from 1979 to 1984.
 After racing in the North American Formula Super Vee series in 1977 and 1978, he made his CART debut in 1979 driving for Spike Gehlhausen at Ontario Motor Speedway.

 He tried 3 races including the Indy 500 in 1982 but failed to qualify for all of them.

McCormack Motorsports is a former Indy Racing League team owned by Dennis McCormack that operated from 1996 to 2001.
 Based in Avon, Indiana, the team debuted at the 1996 Indianapolis 500 with a car for Randy Tolsma, however, it failed to make the field.
 For the 1996–1997 season, the team used 3 different drivers.
 Raul Boesel drove the entire 1998 season for the team and finished 20th in points with a best finish of 8th.
 1999 was another season of instability as the team saw 4 different drivers start a race for them and one other driver, Nick Firestone, fail to get his McCormack entry into the Indy 500.
 2000 again saw 3 different drivers drive for the team and relative instability and lack of funding, along with two of its cars, this time driven by Ronnie Johncox and Robby Unser again fail to qualify for the Indy 500.
 This was largely due to a disastrous experiment with using the uncommon Riley & Scott chassis.
 The team also formed an alliance with the Byrd brothers of Byrd Motorsports and fielded the #30 car for a revolving door of drivers including Johncox, Jon Herb, and J. J. Yeley.
 2001 was the team's final season.
 The team shut down after its car driven by Brandon Erwin failed to qualify for the Indy 500 and then the next week at the Casino Magic 500, where they were woefully off the pace.
 The team's best finish was a 5th place by Boesel at the 1999 Indy 200 at Walt Disney World Speedway.
