Parity Adjustments Spark Controversy at Bathurst 1000 Practice

Late Adjustments Ignite Grid at Bathurst
Controversial Engine Modifications for Ford Mustangs
Just before the 26 competing vehicles hit the Mount Panorama circuit, a decision was made to implement changes to the Ford Mustang entries. These modifications, occurring late into the evening preceding the event, immediately stirred discussion and accusations within the pitlane. Supercars officials had assessed the Ford engines at their workshop, concluding that they were experiencing a power deficit of up to 12 horsepower at higher altitudes from their typical 630-640hp output. Consequently, the air restrictors on the Mustangs were enlarged by 2mm, and their camshaft timing was altered via the ECU. These changes are slated to revert to previous specifications for the subsequent round on the Gold Coast in late October.
Ballast Adjustments for Chevrolet Camaros
Concurrently, the Chevrolet Camaro vehicles also underwent a recent parity alteration, specifically regarding the ballast carried within their rollcages. The previous 4.4kg (8lbs) weight was replaced with a lighter 0.8kg (1lb) ballast. This sequence of late adjustments prompted strong reactions from team personnel, notably from Adrian Burgess, the team manager for Team 18.
Team Managers Express Disappointment
Adrian Burgess voiced considerable dissatisfaction with the timing and nature of these decisions. He highlighted the recurrence of similar discussions from the previous year, expressing frustration that critical information was only provided at 9:20 PM on the night before track activities began. Burgess indicated that further meetings would be necessary to seek clarification and potential resolutions regarding the unexpected changes.
Practice Sessions Under Scrutiny
Despite the off-track controversy, both Ford and Chevrolet teams demonstrated competitive performances during the practice sessions. Kai Allen, driving a Grove Racing Ford Mustang, achieved the fastest time in the initial session, recording a lap of 2m05.8586s. Lochie Dalton, piloting an Erebus Motorsport Chevrolet Camaro, came remarkably close to matching this time in the second session, which was exclusively for co-drivers. Drivers noted the dusty and somewhat challenging conditions of the Mount Panorama circuit, with teams primarily focusing on allowing co-drivers to gain experience and preparing brakes for upcoming practice and qualifying sessions.
Performance Dynamics and Toyota's Debut
In the opening session, Allen maintained a substantial lead over his competitors, finishing almost a quarter-second ahead of Chevrolet drivers Jayden Ojeda (PremiAir Racing) and the experienced David Reynolds, who strategically utilized fresh tires towards the end of the session in his Team 18 Camaro. The afternoon session saw Dalton narrowly outpace the seasoned duo of Scott Pye (Triple Eight) and Tim Slade (Grove Racing). Dalton's performance was particularly commendable, given he was also competing in the second-tier Super2 events in a Ford Mustang for the Blanchard Racing Team. James Courtney secured fourth fastest in Reynolds' Camaro, followed by his teammate and former race winner, Lee Holdsworth. The Toyota teams, making their Bathurst 1000 debut with the GR Supra, faced a challenging day, with none of their cars ranking in the top half of the field during either session. The leading Chaz Mostert/Fabian Coulthard Supra placed 17th, nearly two seconds off the pace, as the team grappled with the green track conditions. The second session offered little improvement for Toyota, with Jordan Boys and Bryce Fullwood (Brad Jones Racing teammate) finishing 15th and 17th respectively. The WTWG cars driven by Coulthard and Jaxon Evans lagged significantly due to various issues, including brake problems. The teams are scheduled to return to the track on Friday for two more practice sessions and a crucial 40-minute qualifying session.
