Bathurst winner Todd Kelly has elected to postpone the debut of a new race car following the successful test of his revamped Jack Daniel's Racing Holden V8 at Winton in Australia last week.
Kelly was expected to introduce the latest Perkins-built VE Commodore at this weekend's inaugural street
race in Hamilton.
But team owner Larry Perkins, disappointed with recent performances in Sydney and the Australian grand prix in Melbourne, ordered a review of the current cars.
"Our results weren't what we wanted and I accepted that we needed to find out why; we needed to rectify the situation rather than debut the new car," Perkins said.
The team were able to recognise a number of deficiencies in the front and rear suspension, areas overlooked last season while getting rookies Shane Price and Jack Perkins up to speed.
"With Todd's experience to draw on, we've been able to identify the shortcomings and make the necessary changes," he said.
Kelly, 28, said:
"Our test was very good; my car is now more responsive and feeling the way I like it - and that has to be better."
