Car #2 back from the dead!

The Holden Racing Team has repaired the Commodore VF crashed at last year's Supercheap Auto Bathurst 1000 as part of a plan to keep two fresh V8 Supercars in reserve in case of emergencies.

Although Garth Tander said he was unsure whether the car would ever race again, it now sits complete in Walkinshaw Racing's Clayton workshop.

The car contested only three events before its huge shunt during Saturday practice at Bathurst with Pirtek Enduro Cup co-driver Warren Luff at the wheel. The brakes failed at turn two and after clipping Craig Lowndes' Red Bull Holden, it careered into the fence, ended up on its side and was subsequently withdrawn from the race.

With another brand new Commodore V8 Supercar also close to completion, team boss Adrian Burgess confirmed Tander's refurbished racer would be one of two back-ups.

"I don't see or believe we have any issues with the chassis we have at the moment. It's more a case of having them available if we have an incident somewhere," he explained.

"Half the cage was replaced and the floor and everything," Burgess told v8supercars.com.au regarding the work done on the Bathurst wreck. "It's pretty much a new car again."

Burgess said he saw no imperatives to replace the existing cars, "As long as they haven't had any big hits and you are looking after them I don't think there is any reason to keep swapping them.

"All you are going to do is go to an event with no ability to test the car beforehand ... and with more variables and more opportunity to have a bad weekend because something has gone wrong with the build process."

Meanwhile, Brad Jones Racing has built a new car for Championship front runner Fabian Coulthard, which is planned to debut in Darwin.

"Tallulah's sister," Coulthard said, referring to car #14's 'name' (many drivers name their V8 Supercars). "Should hopefully be ready for Darwin; that's its scheduled 'birth', I guess."

Coulthard has no issues with the car he is currently racing - "but there's nothing like a new baby, is there?"

Tekno Autosports will move Shane van Gisbergen into the new chassis prepared earlier this year. The team pushed the change back to Darwin so it could run back-to-back from Perth to Winton, and head straight from the west to Victoria given the two week turn around.

While it is expected to be slightly upgraded with new parts from technical partner Triple Eight Race Engineering, van Gisbergen talked down the potential for a dramatic performance increase from the new car.

"There is a little bit, but it's only little stuff that adds up always," the Darrell Lea STIX driver said.

"The car will be much nicer of course, because it is new and well prepared. It will just be better, it won't be magic fix but it will make it nice to drive."

He confirmed the team would continue working in its own technical direction rather than morphing into a Triple Eight clone.

"We are sort of sticking with what we have for now because it does seem to be working. It is a fair bit different to their car but there may be some new bits on the new car coming."

Lucas Dumbrell Motorsport is also aiming to complete a chassis swap for Tim Blanchard, who will move to Nick Percat's repaired car, after it was crashed at Grand Prix. That accidentforced the team to purchase a new rig from TEKNO for Percat ahead of the Tasmania round, while Blanchard's current chassis will betransformed back into Ingall's last race car, a significant collectors item for sponsor Phil M founday.

Volvo and Nissan have upgraded since the season start to counter-act crashes and issues, DJR Team Penske continues its 'rolling chassis' plan, and Triple Eight is building a new chassis, though it is not scheduled to debut this season.
