Vehicle Manufacturer: Year and Model: Ford Mustang Boss 302 (2012) and GT Competitors needing a specification that is not listed should contact the World Challenge Technical Department to find out when that specification will be available and should not make assumptions as to what these specs might be unless otherwise directed to do so by the World Challenge Technical Department. WC Vision Technical Department E-Mail: competition@wcvision.com This specifications form was developed by SCCA Pro Racing and will be used by the PWC Technical Manager to establish technical compliance for vehicles competing in the Pirelli World Challenge series. The Technical Manager can also use, but is not limited to also using the following items to check compliance: Electronic Parts Catalog (EPC), Technical Information System (TIS), and the FIA/ASN Homologation forms (or equivalent documentation). The specifications within this form include all modifications that have been approved by SCCA Pro Racing specifically for the vehicle model(s) and year(s) listed on this page. The parts, specifications and assemblies used shall be those for the unmodified stock vehicle, those permitted within the PWC Technical Regulations and/or within this VTS. If the stock parts, specifications and/or assemblies exceed the performance potential of those approved with this form, then the parts, specifications and/or assemblies used shall meet those listed within this form. Refer to PWC Technical Regulations and Appendix A. for rules regarding all vehicle specifications not specifically listed within the VTS. The most current rules can be downloaded from the official website: race.world-challenge.com and look for the latest Technical Bulletins, Participant Bulletins, and Appendix A. The Vehicle Technical Specification sheet is a permissive document. The exact configuration of any modification allowed within this VTS is subject to the approval of the Technical Manager.
