2006 Vehicle Technical Specifications - SCCA Pro Racing

2006 Vehicle Technical SpecificationsVehicle DevelopmentDRAFTApproved for RacingVehicle___A4 B5 Quattro__ Class__Touring__This draft of the listed vehicle’s VTS is posted with the specifications that we currently have for thevehicle. If a specification is highlighted in green, we are waiting to acquire that information from themanufacturer, or from certified documentation provided by the team(s). If a specification is highlightedin yellow, that specification is under review and may not be set until all blanks in the VTS sheet arecompleted. The specifications that are listed, and not highlighted, are considered to be a work inprogress and may be changed without being posted by technical bulletin. Therefore, competitors mayuse the specifications listed to begin preparing their vehicles. The missing specifications will be addedas they are received.When a vehicle is in this draft form, it will be permitted to compete in any World Challenge competitions.Once the World Challenge Technical Staff has determined that this specific vehicle has demonstratedreasonable performance in relationship to other cars competing in the series and all specifications havebeen obtained, then this VTS sheet will be removed from DRAFT status and transformed into a finalVTS. From that time forward, all changes to the VTS will be subject to Type II approvals.Competitors needing a specification that is not listed should contact the World Challenge TechnicalManagers to find out when that specification will be available and should not make assumptions as towhat these specs might be unless otherwise directed to do so by the World Challenge TechnicalManagers.Touring Car Teams should contact:Shawn Passen(614) 419-2851 Office(785) 608-9261 Mobilespassen@sccapro.comGrand Touring Teams should contact:Harry Turner(785) 608-9382hturner@sccapro.comDate Issued: 03.10.2006 Revision #: Draft Revision Date:1 11/01/04

2006 Vehicle Technical SpecificationsVehicle___A4 B5 Quattro__ Class__Touring__2006 WORLD CHALLENGE SEASONVEHICLE MANUFACTURER:AudiYEAR & MODEL: -02 A4 Quattro 1.8tThis specifications form was developed by SCCA Pro Racing and will be used by the SeriesTechnical Administrator to establish technical compliance for vehicles competing in the SCCAPRO RACING WORLD CHALLENGE series. Technical Administrator can also use, but is notlimited to also using the following items to check compliance: Electronic Parts Catalog (EPC),Technical Information System (TIS), and the FIA/ASN Homologation forms (or equivalentdocumentation).The specifications within this form include all modifications that have been approved by SCCAPro 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, thosepermitted within the Pro Racing Regulations (PRR) and/or within this VTS. If the stock parts,specifications and/or assemblies exceed the performance potential of those approved within thisform, then the parts, specifications and/or assemblies used shall meet those listed within thisform.Refer to SCCA PRR for rules regarding all vehicle specifications not specifically listed within theVTS. Specifications regarding wheels and tires may be found in Article 3 and Appendix A of thePRR. Specifications regarding brakes may be found in Article 3 of the PRR. Appendix A will listwhat size restrictor to use if a restrictor is required to be run.When looking for the most current rules, go to www.world-challenge.com and look under the“Competitors” section for latest Technical Bulletins, Participant Bulletins, and Appendix A.This Vehicle Technical Specification sheet is a permissive document. The exact configurationof any modification allowed within this VTS is subject to the approval of the TECHNICALADMINISTRATOR.Note: this form will have measurements in both U.S. Standard and Metric units of measurewhen practical. U.S. measurements will be in parenthesis.Date Issued: 03.10.2006 Revision #: Draft Revision Date:2 11/01/04
