Supercars has confirmed that pre-race parc ferme will apply at next month’s Ipswich SuperSprint, with tyres to be included in the procedure and Super2 to have its own version.

Parc ferme between Armor All Qualifying and the following race was first trialled for both races at Symmons Plains in April, where teams were only allowed to conduct minor work on cars during such time.

While there had been some calls to prohibit refuelling between qualifying and racing, cars will instead have to race on the same tyres as they ended qualifying on.

The Queensland Raceway Championship supplementary regulations state that, “Wheels may be loosened; however, all four (4) wheels must remain on the Car at the completion of the Cars last qualifying run.”

As such, tyres cannot even be swapped from one corner to another, which might also have provided a slight benefit in optimisation of tyre life.

“The feedback after Tasmania was very positive,” Supercars Head of Motorsport Adrian Burgess told the championship’s official website.

“At the start of the year we agreed to do Tasmania and QR for the main series and after debriefing Tassie, we’ve elected to trial it in Super2 for one event as well.

“Adding tyres to the mix (for the Championship) is not a big deal, but it’s an extension of the ‘what you’ve got is what you’ll race with’ formula.

“At the Commission we discussed doing the same thing with fuel as well, but we weren’t comfortable that we could do that without impacting some more than others.”

As previously reported, Supercars has also moved to restrict data collection from pit stops in a bid to reduce costs, which takes effect from the next event in Townsville.

Further Supplementary Regulations for the Watpac Townsville 400 state that, “Pressure Sensors are not permitted to be affixed to any air line connected to an air impact tool or air lance,” and that, “Teams are not permitted to use a data logger affixed on any pitlane equipment.”

The Townsville 400, which encompasses Event 8 of the Virgin Australia Supercars Championship and Round 3 of the Dunlop Super2 Series, takes place on July 5-7, while the Century Batteries Ipswich SuperSprint, which takes in Event 9 of the Championship and Round 4 of Super2, follows three weeks later.
