Discussions about parity had returned in 2000, with 100 millimetres trimmed from the front spoiler of the Commodore after Holden, in particular, the Holden Racing Team, had dominated in 1998 and 1999. This was in response to the 300 mm removed from the Falcon in previous seasons, and coincided with a 10 mm trim from the Falcon's rear spoiler. The small reduction for the Holden teams was quickly addressed with both cars receiving the same front splitter shortly afterwards, but the Falcon's rear wing remained trimmed. Ford had threatened to withdraw from the series, but nothing came of this. After Holden again dominated in 2001 and 2002, a new set of regulations, dubbed 'Project Blueprint', was introduced in 2003 to close the performance gap between the Commodore and the Falcon, thus creating closer, fairer racing. Project Blueprint was developed by Paul Taylor and Wayne Cattach, who spent two years designing a formula which would eliminate most of the differences between the Fords and Holdens.
