IndyCar has fined Team Penske $35,000 and docked it 15 entrant points because the underwing on Helio Castroneves' race-winning car at Texas didn't meet specifications.
Series officials said a post-race inspection found that the car didn't comply with a rule requiring the "exit of the underwing height" to be 7.6 inches. Team Penske said it found the height was instead 7.575 inches "because we neglected to tighten" braces positioning the rear of the diffuser.
Penske Racing President Tim Cindric said the mistake didn't provide Castroneves any advantage in the race, which ended with the team's first victory of the season. Castroneves led the final 132 laps and finished 4.7 seconds ahead of Ryan Hunter-Reay.
