I2.4 Minor Non-Compliance 2.4.1 The CTM, having noted an area of minor non-compliance, may endorse the Car’s Motorsport Australia log book with an entry regarding rectification of the non-compliance. 2.4.2 Having so endorsed the Car’s Motorsport Australia log book, before the Car is permitted on to the Circuit, the CTM must send to the Stewards the Car’s Motorsport Australia log book and a note in the following form: I2.4 2.4.2.1 “In my view, the minor non-compliance noted in the log book of this Car does not improve the performance to such an extent that the Car should be disqualified from this Event, and thus it may compete in this condition for this Event only.” 2.4.3 Upon receipt of the note referred to in Rule I2.4.2, the Stewards may then permit the Car to participate in the Event subject to the endorsement being countersigned by the Stewards in the Car’s Motorsport Australia log book. 2.4.4 I2.4 If the Stewards have specifically approved the participation of a Car notwithstanding an endorsement in its Motorsport Australia log book pursuant to Rule I2.4.1, then no protest or appeal on that ground by any other person will be accepted in respect of that Event. 2.4.5 Where a question of eligibility is raised during or after Competition and that matter would have been treated as a “minor ineligibility” if raised at scrutiny the Stewards may treat the matter post event in the manner as determined above. I2.5 I2.5 Repairs 2.5.1 Any repairs or replacements must take full account of engineering integrity and safety. 2.5.2 The CTM has the right to consider the engineering integrity and safety of any modifications carried out and to require corrective action if appropriate. 2.5.2.1 Should the CTM deem it necessary to inspect any repairs, all costs incurred by Supercars to carry out required inspections must be met by the Competitor. 2.5.3 Restoration of Bodywork and Chassis geometry following accidental damage is permitted I3.1 only using approved panels and parts or by the addition of materials necessary to affect the repairs (e.g.: body filler, weld metal). 2.5.4 Any repairs to the Chassis must respect the Design. © Supercars – 2024 Division “I” Page I5 of I72 2024 FINAL I3. SCRUTINEERING I3.1 Targeted Scrutiny 3.1.1 In Australia, each Car will be subject to the provisions of the targeted scrutiny program for each Event.

This guard may take the form of a change in material and/or I4.2 construction of the boot side infill panels or a specific shroud for the filler necks. Any such guard must have written approval of the CTM prior to being used in competition. Any such guard may be fitted to both sides regardless of which side the fillers are fitted. 4.2.9 It is permitted to brace between the base of the “C” pillar and the rear Chassis rail.
