<strong>Vehicle</strong> <strong>Technical</strong> <strong>Specifications</strong><strong>Vehicle</strong>: Volvo S60 Class: GT<strong>DRAFT</strong> <strong>VTS</strong>Approved for <strong>Racing</strong><strong>Vehicle</strong> Manufacturer:Year and Model:Volvo(04-09) S60This draft of the listed vehicle’s <strong>VTS</strong> is posted with the specifications that we currently have for the vehicle. If aspecification is highlighted in green, we are waiting to acquire that information from the manufacturer, or fromcertified documentation provided by the team(s). If a specification is highlighted in yellow, that specification isunder review and may not be set until all blanks in the <strong>VTS</strong> sheet are completed. The specifications that are listed,and not highlighted, are considered to be a work in progress and may be changed without being posted bytechnical bulletin. Therefore, competitors may use the specifications listed to begin preparing their vehicles. Themissing specifications will be added as they are received.When a vehicle is in this draft form, it will be permitted to compete in any World Challenge competitions. Oncethe World Challenge <strong>Technical</strong> Staff has determined that this specific vehicle has demonstrated reasonableperformance in relationship to other cars competing in the series and all specifications have been obtained, thenthis <strong>VTS</strong> sheet will be removed from <strong>DRAFT</strong> status and transformed into a final <strong>VTS</strong>. From that time forward, allchanges to the <strong>VTS</strong> will be subject to <strong>VTS</strong> change request approvals.Competitors needing a specification that is not listed should contact the World Challenge <strong>Technical</strong> Department tofind out when that specification will be available and should not make assumptions as to what these specs mightbe unless otherwise directed to do so by the World Challenge <strong>Technical</strong> Department.<strong>SCCA</strong> <strong>Pro</strong> <strong>Technical</strong> DepartmentE-Mail: tech@sccapro.comPhone: (785) 357-7223Fax: (785) 233-7223Packages: 6700 SW Topeka Blvd.Building 300Topeka, KS 66619Date Issued: 3.9.2009 Version Number: 9 Version Date: 6.11.2010 Page: 1 of 7
<strong>Vehicle</strong> <strong>Technical</strong> <strong>Specifications</strong><strong>Vehicle</strong>: Volvo S60 Class: GT<strong>Vehicle</strong> Manufacturer:Year and Model:Volvo(04-09) S60This specifications form was developed by <strong>SCCA</strong> <strong>Pro</strong> <strong>Racing</strong> and will be used by the TECHNICAL MANAGER toestablish technical compliance for vehicles competing in the <strong>SCCA</strong> PRO RACING WORLD CHALLENGE series. TheTECHNICAL MANAGER can also use, but is not limited to also using the following items to check compliance:Electronic Parts Catalog (EPC), <strong>Technical</strong> Information System (TIS), and the FIA/ASN Homologation forms (orequivalent documentation).The specifications within this form include all modifications that have been approved by <strong>SCCA</strong> <strong>Pro</strong> <strong>Racing</strong>specifically for the vehicle model(s) and year(s) listed on this page. The parts, specifications and assemblies usedshall be those for the unmodified stock vehicle, those permitted within the <strong>Pro</strong> <strong>Racing</strong> Regulations (PRR) and/orwithin this <strong>VTS</strong>. If the stock parts, specifications and/or assemblies exceed the performance potential of thoseapproved within this form, then the parts, specifications and/or assemblies used shall meet those listed within thisform.Refer to <strong>SCCA</strong> PRR and Appendix A. for rules regarding all vehicle specifications not specifically listed within the<strong>VTS</strong>.The most current rules can be downloaded from the official website: www.world-challenge.com and look under the“Competitors” section for latest <strong>Technical</strong> Bulletins, Participant Bulletins, and Appendix A.This <strong>Vehicle</strong> <strong>Technical</strong> Specification sheet is a permissive document.
