Although IndyCar CEO Randy Bernard said during the Detroit Grand Prix weekend that he had smoothed his relations with the IZOD IndyCar Series team owners, SPEED's Robin Miller reports that the owners also made clear in meeting with Bernard that they want to delay – again – the planned introduction of new, independently sourced aero kits for the Dallara DW12 chassis.

The kits, which were conceived as a cost-effective way to provide variety as well as a unique look for each manufacturer, were originally supposed to be part of the package introduced with the new cars and engines this season. However, Bernard agreed to delay their introduction until 2013 after team owners all but unanimously expressed concerns over the associated start-up costs. Now, according to SPEED's report, they want the kits postponed again.

“We're all in agreement that nobody wants new aero kits next year because it's not really necessary right now,''  Dennis Reinbold told Miller. “We've got a really good racecar right now and the competition level is good so it's just an extra expense we don't need.''

Bobby Rahal confirmed to AUTOSPORT that bodywork was among the issues raised at the meeting of Bernard and the owners.

"Some of the concerns [from the teams] are about cost," he said. "But some of it is also the ability to fix carbon work in non-sanctioned places."

Rahal is hopeful that the issue will be dealt with quickly.

"I thought the meeting was very constructive," he said. "I don't think there were any real answers, but the owners certainly made their case and the atmosphere was respectful. I think now IndyCar has to go back and deal with the concerns that the owners have, and we expect to hear something in the next couple of weeks."

Chevrolet, Honda and Lotus have already expressed an intention to build their own bodykits in 2013, while Dallara has also explored creating an alternative aero kit ether under its own name or on a contract basis for another company. The kits are expected to cost $75,000 each, with teams needing separate kits for road/street courses and ovals.
