COMPLIANCE G2.1 G2.1 General 2.1.1 A Car must comply with the Design, relevant VSD, ESD and the Rules. 2.1.2 A Car must be constructed in accordance with the Design and comply with all aspects of the relevant VSD, ESD and the requirements of the Rules. 2.1.3 A Car must comply with the relevant sections of Article 277 of Appendix J Category II SH to the ISC of the FIA. 2.1.4 All Control Parts are listed in Schedule G1 and must always comply with the definition of a Control Part. 2.1.5 Each Competitor is responsible for ensuring that their Car complies with the conditions of G2.1 eligibility contained in the Rules throughout each Event and all Supercars authorised activities including all rides and at a Supercars Test Days as described in Rule D1, unless authorised by the CTM. 2.1.5.1 The testing of non-Homologated parts must be requested in writing to the CTM for approval. 2.1.6 The acceptance of the targeted scrutiny declaration conditions will be deemed to be an implicit statement by the Competitor of conformity with the Rules. 2.1.7 It is the Competitor’s responsibility to ensure all required Supercars seals are affixed prior G2.2 to the first qualifying Session at an Event. 2.1.7.1 It is the Competitor’s responsibility to ensure all Supercars seal affixed by any Supercars’ official remains intact. 2.1.7.2 No Supercars seal may be removed at any time without prior written approval of the CTM. G2.2 Examination for Eligibility 2.2.1 Should the CTM suspect at any time that a Car does not comply with the Rules, the Competitor, or Authorised Representative, must be so advised and given the opportunity to comment on the suspected or alleged ineligibility. G2.2 2.2.2 Any comment so made may be recorded by the CTM, and subsequently may be presented at any Stewards’ Hearing. 2.2.3 Should the CTM fail to receive an adequate comment on the suspected or alleged ineligibility, which the CTM alone has sole discretion to consider as adequate, the CTM may require the Car or component to be impounded and examined, including such dismantling as may be necessary, to determine the points of eligibility in question. 2.2.4 At the direction of the Stewards, any components or parts of a Car may be sealed by the G2.2 CTM for examination by the CTM. 2.2.4.1 For any item sealed and/or identified by any means by the CTM, it is the Competitors responsibility to ensure the item, which may include removable part/s, complies with all conditions of eligibility contained in the Rules. 2.2.4.2 With a view to facilitate scrutineering at the Race Track, each Team is required to: a) Have available sufficient sets of long damper mounting bolts that have been drilled to facilitate the passage of 1.5mm diameter lock wire.

G2.4 Minor Non-Compliance 2.4.1 The CTM, having noted an area of minor non-compliance, may endorse the Car’s G2.4 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: 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." G2.4 2.4.3 Upon receipt of the note referred to in Rule G2.4.2, 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 If the Stewards have specifically approved the participation of a Car notwithstanding an endorsement in its Motorsport Australia log book pursuant to Rule G2.4.1, then no protest or appeal on that ground by any other person will be accepted in respect of that Event. G2.5 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. G2.5 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. G2.5 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 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 – 2026 Division “G” Page G4 of G76 G3.1 2026 FINAL G3.

in the airstream going to the Driver’s helmet. This is only required to be transmitted if a sensor is installed. *** This channel must be “Fuel Mixture Aim – Hi Res” as received from the ECU in the 0x6C0 message block. † Fuel Flow - Teams are free to select the source of this channel. †††† Fuel Mixture Aim Driver Trim must originate from message ID 0737 of the 0x730 message G16.3 block. ‡ PDM output related channels that must be transmitted. ^ Battery Voltage - Must be PDM voltage ^^ Display Page – output channel from the display selection tab of the display set-up in dash manager. § Channel may be ignored if a representative channel is not generated.
