0.0 Technical Rules and Regulations Overview It is the mission of Pirelli World Challenge (PWC) to allow ALL manufacturers, teams, sponsors and promoters the opportunity to compete in the highest level of “Sprint” road racing competitions. With classes from showroom stock to the premier luxury brands in GT3. All competing vehicles must be identifiable with the vehicles offered for sale to the public through the manufacturer’s normal distribution channels. NOTE: Everything that is not expressly permitted in these regulations is prohibited. Permitted technical modifications must not result in any illegal modifications or infringements of the Regulations. These regulations combined with the sporting regulations (SR) form the general regulations for PWC. A full description of rules interpretation and use of English text is listed under SR Section 1.1 Racing begins with “safety first” and for this reason we have moved the safety Appendix to the start of the Technical Regulations. Any references to the FIA or SFI rules uses the same numbering convention for compatibility and ease of cross reference 1.0 SAFETY APPENDICES, REGULATIONS 1.1 APPENDIX C - FIRE EXTINGUISHER SYSTEMS Only homologated extinguisher systems listed on “FIA Technical List No.16”, “FIA Technical List No.52”, or “SFI spec 17.1” are permitted. All Installations must follow MANUFACTURERS specifications.
It is a mandatory requirement that all extinguishers must: a) Be situated within the survival cell at a distance greater than 300mm from outer edges of bodywork. b) Operate in any position, even if the car is inverted. c) Have a self-test method for either pressure checking systems on FIA Technical list 6 or the triggering mechanism
in the NON-pressurized systems listed on Technical list 52. d) Withstand a deceleration of 25g and operate between temperatures of –15 Deg. C to +80 Deg. C. e) Be removable for verification of full charge. f) Be capable of being activated by the driver whilst belted in the seat. g) Use a trigger system independent of vehicle electrics with a secondary EXTERNAL cut-off switch or cable. The
switches location must be indicated by a E fire decal of ∅10cm. h) Be serviced and recertified by the manufacturer every two years. i) Must have a current label similar to the examples shown below:

1.2.1 Geometric Locations The geometrical locations of the anchorage points are shown in Drawing 253-61. Shoulder straps must be directed towards the rear and not making an angle of more than 45° to the horizontal from the upper rim of the backrest. It is preferred that this angle should not exceed 10°. Maximum angles in relation to the centre-line of the seat are 20° divergent or convergent (shoulder straps may be installed crosswise symmetrically about the centre-line of the front seat). 1.2.1.1 FIA ART 253-61 Restraint Locations

1.2.2 Anchorage Points The lap and crotch straps shall only pass through the seat. All lap straps must fit tightly in the bend between the pelvic crest and the upper thigh. Under no conditions must they be worn over the region of the abdomen. Care must be taken that the straps cannot be damaged through interference, twisting, edge loading or chafing against sharp edges. Two-inch lap belts are highly recommended as they have been shown to provide faster loading of the lap belt resulting in lower loads to the chest, head, and neck. Their fitment around the pelvis is better allowing the belt to be worn tighter while being more comfortable and easier to adjust. 1.2.3 FIA ART 253-62, 63 Anchorage Mounting Seat belts cannot be anchored to the seats or their supports. Approved mounting techniques are shown below
1.2.4 Shoulder Strap Mounting The shoulder straps may be fixed to the safety cage by means of a loop, (as per FIA Drawing 253-66). The tube used must be as per the roll cage specifications. 1.2.4.1 Shoulder Strap Mounting (Figure 8) The formula Y = Z - (X *.40) can be used to determine the “ideal” distance between attachment points (see figure 8). Where the shoulder belts are wrapped around a harness bar, the “Y” dimension is measured from the center line of the webbing of each shoulder strap. Where the shoulder belts are bolted the “Y” dimension is measured center to center of each mounting bolt. 1.2.5 Three Bar Adjusters 3-bar adjusters may be used for wrap mounting shoulder belts around harness bars or leg straps around mounting bars. They shall be placed as close to the mounting points as possible. Figures 12-15 show the correct wrapping techniques which must be adhered to. Refer to TR 1.5 on dimensions of mounting bars

1.3 APPENDIX K - SEAT AND HEADRESTS
Only unmodified “racing” seats to FIA 8855-1999, FIA 8862-2009, or a SFI 39.1/39.2 are permitted. FIA 8855-1999 seats must be on FIA tech. list No. 12. Expiration is five years after manufacturer date. FIA 8862-2009 seats must be on FIA tech. list No. 40. Expiration is ten years after manufacturer date. SFI Seats must meet on SFI 39.2. All Seats must be capable of withstanding 200 lbs. of rearward force. Any material covering seat including driver seat inserts must be of an approved fireproof material. All seats must be rigidly mounted to the vehicle structure in accordance with TR 5.12 and TR1.2.1. GTS, TC, TCA cars require leg support bracing to limit side-to-side movement of the legs. The plate should
begin flush with the thigh supports and continue forward as far as possible. If possible the plate should be covered with foam and a fireproof material.

1.4 APPENDIX I - FUEL CELL SPECIFICATIONS 1.4.1 Fuel Bladder Criteria
Only bladders meeting and certified to FIA spec FT3-1999, FT3.5 or FT5-1999 are permitted. Produced by a manufacturer on “FIA Technical list 5” are permitted for use. Contain an internal fuel cell foam approved by the manufacturer. The material shall fill all internal space while not
impeding the function of other fuel system components. They shall be replaced, or recertified, after five (5) years from the date of manufacture. Any recertified cell may only be used for a further two years. PWC also reserves the right to disallow the use of a fuel cell. Have an official certificate from the manufacturer listing expiration date. Display the approved unaltered FIA decal as shown below.
Old label valid until Dec 2017 New Label Jan 2013 -
1.4.2 Fuel Bladder Protection All Bladder tanks must be enclosed in a fabricated “container” separating itself from the cockpit. “Container” location must be within the width of the chassis and as close to the centerline of the vehicle. Fabricated “container” must fully surround the bladder. Placed rearward of an imaginary vertical plane described in the general regulations on seat location. Use a minimum material thickness of 0.036” 0.91mm steel or 0.056” 1.42mm aluminum. Located at least six- inches (6”) above ground unless enclosed completely within the bodywork.
1.4.3 Fuel Hoses and Fittings Fuel fittings include all openings, breathers, vents, plumbing, test ports and fill lines. Fuel fittings must fully contain all fuel if the vehicle is partially or fully inverted. All fittings must be Isolated from the driver, so in case of leakage, or failure, fuel will not reach the driver. Fuel Lines “passing through” the cockpit must be continuous except at the firewalls Art 253-59,253-60 below. Ventilation lines must be to the same specifications as fuel lines, vent outside the car and fitted with:
Gravity activated roll-over valve, Float chamber ventilation valve and a blow off valve. A Blow-off valve (max pressure 200mBar) working when float chamber ventilation valve is closed. Vent lines greater than φ20 mm ID must use an approved non-return valve FIA Art 253-14.5.
1.4.4 Fuel Filler Cap
Positive locking system within surface of the bodywork. (flip top Monza style prohibited). Have a mandatory check valve installed unless located directly on fuel cell with a locking unvented cap. Check valves must prevent fuel escaping if the cap and filler neck are torn from the bladder. A filler neck connecting the filler cap and the fuel bladder need not be bulk headed. Filler neck must contain a minimum of two sections connected by a high quality, flexible, hose that is:
Resistant to automotive fluids, allow for misalignment of filler tubes. Be of a design that will not “crack” the fill tube in event of an accident. Minimum distance between two fixed pipe sections is (10”) with connecting hose overlapping (>1”).

2.1 TECHNICAL INSPECTION 2.1.1 Team Representative
Designated representative (a single person, not multiple) who may OFFICIALLY speak for the team. Designee for any protests or appeal submissions or changes to entry or credential information. Changes to the designated representative must be in writing to the Series Administration. A Driver(s) cannot be a team representative unless they are the only team member. In the case that the primary representative is incapacitated, an alternative may be designated
2.1.2 Event Inspection
At each event, all vehicles will be given a schedule time for an inspection of their vehicle for compliance. All Driver(s) safety equipment (fire suits, helmets etc.) will also be inspected for compliance A maximum of 3 team members are permitted during official inspection.
2.1.3 Vehicle Declaration Sheet To be submitted at each event prior to qualification, where details from the previous declaration have changed. Penalties up to disqualification may be applied for non-compliance. The Vehicle declaration summarizes vehicle parameters and “current” seals fitted to the vehicle. The competition department will move to allowing electronic submission of this information in 2017 2.1.4 Annual Inspection It is required for all vehicles in the series for compliance with sanctioning body and series insurance
It must be completed at first event of the year the vehicle competes in Inspections follows form(s) shown in TR 10.9 available on series web site A Compliant vehicle will receive a USAC tamperproof “ID No.” decal. The Decal will be mounted to the RHS B-pillar.
Tampering or removal is prohibited with penalties The Annual inspection serial number links all recorded vehicle information to the vehicle
2017 Annual PWC Decal
2.1.5 Re-Inspection Any compliant vehicles involved in incidents resulting in crash damage may have the tech sticker removed by an
official. After the vehicle is satisfactorily repaired it will need complete another annual inspection
2.1.6 Inspection – Vehicles Selected
Concluding any official session, vehicles will be selected by the PWC TECHNICAL MANAGER for verification of legality The series will determine which items are to be inspected and may request removal of parts from a vehicle. Entrant(s) shall stand the expense of disassembly, inspection, and reassembly. The competition department may request “parts”, for analysis of performance capabilities. “Parts” can be single or
multiple components, complete cars, or engines Entrants shall take all necessary steps to enable any tests requested. It should be noted that WCV and USAC will
work with manufacturers first to collect such information to prevent disruption to teams. The PWC Technical Manager may also seal, or impound, cars, parts, and/or equipment for this purpose. Neither PWC, WCV nor USAC are responsible for any loss or damage resulting from such analysis. Any results will typically remain provisional whilst such inspection or analysis takes place.
Manufacturers or entrants may request that any additional inspections are completed off site. If the request is approved any and all costs for PWC to attend will be charged to entrant. A typical example would be disassembly of an engine at the engine builder’s premises.

2.2 OFFICIAL MEASUREMENT The official scales [sporting article 1.12.1] are available for teams as specified in the event schedule except when being used for scrutineering. All dimensional measurements will be made using the official scales while the car is stationary on the flat horizontal surface without the driver in the vehicle. 2.2.1 Weight PWC will publish Base Weights for each vehicle in Appendix A. They will apply to the vehicle with the official driver weight but without fuel. The series may request any race class to pump out all the fuel in Parc Fermé to verify the weight. If requested, only that race class will be required to pump out fuel – not the entire race group. 2.2.2 Driver Weight Each driver must officially weigh in, with driving equipment before qualifying. If during any inspection the car weight is within +/- 5 lbs. of minimum weight, the officials may request for the driver in his gear to be seated in the vehicle. Drivers who do not attend without an official reason will be penalized. The Car/Driver Combination must be greater than minimum weight published in Appendix A. In the example the car is 12 lbs. above the minimum weight.
Appendix A weight 3225 lbs. Car weight dry 3050 lbs. Driver weight for his car 187 lbs. Official weight for the vehicle 3050 + 187 = 3237 lbs.
2.2.2.1 Driver Weight Multiple Drivers For races with multiple drivers in the same race such as SprintX, all weight calculations listed in 2.2.2 apply except the driver is considered the “average” weight of the two drivers 2.2.3 Ride Height The ride heights at designated measuring points cannot be below the minimum values listed in Appendix A. Official measurements are from the series flat pad / surface. Official tire pressures are 32 psi for TC vehicles and 30 psi for GT vehicles. The vehicle must pass on either wet or dry tires. The splitter protrusion will generally be measured at five (5) key points, but must be compliant at any measurement point. Those five (5) key points will consist of the centerline of the car, the approximate center of each front corner, and each end of the splitter in front of the front tire. NOTE: Measurement allowances for a car with severe body damage, chassis damage, or suspension damage that would affect the measuring of the ride height will be on a case by case basis. 2.2.4 Sound Test 2017
All vehicles must meet the WC sound requirements of 110dB (A) or less. The exhaust noise will be measured at 3800 rpm, or at three‐quarter of the maximum revs if this is less. Measurement will be taken at a distance of 0.5m (20”) and at a 45 degree angle to the point of exit of the exhaust.
(This is the same requirements as the FIA Art 257A section 5.3)
2.2.5 Barometric Pressure Test The local Barometric pressure, for each event, will be determined prior to the first official practice day and used to adjust manifold pressure limits for boosted cars listed in Appendix A. See article 10.3.6. Note WC will correct offsets in pressure sensors before applying sensor tolerances.

21 | P a g e
2.3 PWC SEALS All mandatory seals, Engines, restrictors, etc., shall be intact prior to the start of qualifying and races. It is the team’s responsibility to ensure they are officially sealed and recorded prior to qualifying. Broken or incorrect seals to those recorded by officials will result penalties up to disqualification.
2.3.1 Electronic Seals Teams are strongly encouraged to take part in the Pirelli World Challenge Electronic Sealing Program. Teams taking part in the electronic sealing program will generally be exempt from having their engine internals torn down and inspected at the track. Engines may be torn down at the track under extenuating circumstances, such as suspected seal tampering, etc. Teams wanting to take part in the electronic sealing program should contact the PWC Technical Manager for details. 2.4 NON-COMPLIANCE OF VEHICLE Any inspected vehicles found to be non-compliant during or after official sessions are subject to a penalty [sporting article 1.31]. The burden of proof to show that the vehicle is compliant rests with the entrant and not the series. 2.4.1 Non-Compliant Parts Non-compliant parts/components are subject to seizure by PWC and may not be returned. 2.4.2 Non-Compliance Penalty The PWC Technical Manager will document the infraction, citing the rules broken and advise both the team and PWC Competition Director of suggested penalty. The PWC Competition Director will make the final approval for the penalty including interpretation of rules and specifications. Minor infractions such as a bent exhaust clamp causing the car to fail ride height could be given a “Car Repair Order“. If the infractions are not remedied in a timely manner, the penalties increase through fines to loss of times to Exclusion. 2.5 DRIVER SAFETY All drivers must meet the minimum safety requirements outlined in section 1 of the regulations 2.5.1 Driver Exit Test
Driver must be buckled in the race seat wearing all their race clothing. The driver must turn off the master electrical switch, touch the fire system actuator as if activating it, remove the
steering wheel, release the harnesses, window nets equipment etc. Within Fifteen (15) Seconds, exit the vehicle and be standing with both feet on the ground outside the vehicle

PWC will provide the teams with a memory stick/card for purposes of delivering to the series the required session Motec data. Memory sticks/cards remain the property of PWC. The memory stick/card must be deposited at the series transport (tech trailer) within 30 minutes of the end of the session. Teams not turning in the required data, or data stick/card will be subject to penalties from loss of times, track time and/or fines. 10.3.5 Compliance of RPM Cars must not exceed the RPM limit monitored as MoTeC channel ‘PWC_OverRPM’ when the following applies Compliance criteria:
IF (‘Throttle Pos’ > 30% AND ‘Engine RPM’ > 3000 AND ‘G Force Long > 0’ AND ‘Engine RPM’ > ‘PWC RPM Limit’) THEN ‘PWC OverRPM’ = TRUE
NOTE: The channel ‘Throttle Pos’ must be the throttle butterfly and not pedal Position. Dual butterfly systems used on some engines must use the LARGEST butterfly for the channel. 10.3.6: Compliance Boosted Cars
The calculation for OverBoost uses the same STEP function as SRO Blancpain GT Series. Any boosted vehicle must not exceed the Maximum manifold pressures monitored as MoTeC channel ‘PWC Boost
Limit’ at the rpm conditions for the values listed in the Appendix A. The Appendix A boost limit values ‘𝑃𝑃𝑃𝑃𝑃𝑃𝑃𝑃 (𝐵𝐵𝑃𝑃𝐵𝐵)’ are set for reference ambient pressure of 1010 millibar. These
values must be adjusted by the correction factor below at each event to determine ‘PWC BoostLimit’ NOTE Starting Jan 2017:- Sensor offsets will be corrected to the ambient pressure before the sensor
tolerance is applied
Definitions: ‘Pmax’ = Appendix A pressure limits ‘Pamb’ = Local track pressure per article 3.2.5 ‘PWC BoostLimit’ = manifold pressure limits used for compliance ‘CF’= track/event specific ambient correction factor Correction Calculations: 𝐶𝐶𝐶𝐶 = (1010 (𝑃𝑃𝑚𝑚𝑃𝑃𝐵𝐵) − 𝑃𝑃𝑃𝑃𝑃𝑃𝑚𝑚 (𝑃𝑃𝑚𝑚𝑃𝑃𝐵𝐵)) 𝑃𝑃𝑃𝑃𝐶𝐶 𝐵𝐵𝐵𝐵𝐵𝐵𝐵𝐵𝐵𝐵𝐵𝐵𝐵𝐵𝑃𝑃𝐵𝐵𝐵𝐵 (𝑃𝑃𝑚𝑚𝑃𝑃𝐵𝐵) = 𝑃𝑃𝑃𝑃𝑃𝑃𝑃𝑃 (𝑃𝑃𝑚𝑚𝑃𝑃𝐵𝐵) − 𝐶𝐶𝐶𝐶
E.g. For local Barometric pressure of 980 millibar: (1010 mbar - 980 mbar) = 30 mbar offset lower from PWC manifold pressure limits listed on Appendix A.

10.4 REPLAY CAMERAS All teams must use two Replay XD cameras to record every official session. The primary camera shall be mounted on the roof pointing forward. It must be in a
position to record objects 60 feet away at heights from 22-52 inches. Cameras must be mounted right side up and securely mounted to withstand vibrations and a sustained 25-g deceleration.
The 2nd camera must be mounted to the main hoop of the roll cage. It must clearly show the steering wheel and dash.
Teams must provide the primary camera view to series officials after all official sessions, deposited at the series transport (tech) within 30 minutes of the end of the session.
Teams must provide their own memory cards. Minimum SD card requirements are 16 Gb, class 10. See the Replay XD SD card compatibility page for more information on minimum SD card performance requirements. http://www.replayxd.com/sd-card/.
Teams not turning in data will be subject to penalties from loss of times, track time and/or fines. Minimum camera resolution is 1080p at 60 fps, with super wide FOV. This corresponds to a blue ‘mode’ LED, double
orange FOV LEDs, and a green FPS LED as view on the back of the camera when the camera is powered up. 10.5 ON BOARD YELLOW LIGHT SYSTEM
When activated by race control, the system activates “in car” Yellow LED warning lights to illuminate and alert the driver when the course is full course yellow.
All cars must be equipped with the specified yellow light system receiver, antenna, and PWC light. The yellow warning light LEDs must be prominently located on the cars dash in clear sight for the driver and
secondary in-car camera. Antennas must be mounted on the roof. Cars will not be allowed on track during Official Sessions unless the system is installed and is working. Modifications to the system is prohibited. Integration of the warning lights into the Motec shift light system is permitted and recommended. Note: Old IMSA wiring looms are compatible with an antenna adaptor. New IMSA wiring looms are directly
compatible. Systems, and parts can also be purchased directly from the supplier MSE. Contact Bruce Natvig at Phone Number:
765-319-3399 or [email protected]. Receiver Boxes can be rented from PWC on a per weekend basis. Teams renting receiver boxes still must purchase
a complete wiring kit from either MSE, or PWC. Contact Staci Langham at [email protected] for more information.
