The penalty for the No. 6 Porsche Penske Motorsport 963 following Indianapolis, which significantly altered the IMSA WeatherTech SportsCar Championship point spread in GTP going into next weekend’s Motul Petit Le Mans, was the result of a “procedural issue,” says Porsche Penske Motorsport team manager Jonathan Diuguid.

Following the TireRack.com Battle on the Bricks, IMSA conducted in-depth tech inspections of several cars. One of those was the No. 6 PPM 963 that finished third in the six-hour race. IMSA found “modifications to its wiring harness/loom that were outside of homologation,” and the No. 6 was moved to next-to-last in the GTP field. That changed the championship fight from a near-dead-heat between the two PPM cars to a significant margin for the No. 7 team.

While noting that PPM respects IMSA’s procedures and rules, Diuguid notes that the rule violation was not intentional. There also appears to be no evidence that it provided any sort of competitive advantage.
