I. PURPOSE
By defining the rules in this area, we are trying to maximize the numbers of runs for all PCA members competing in the Autocross Series. If an action or modification is not expressly allowed, it should be assumed to be illegal. Disputes over rules interpretation will be decided by the event chair in consultation with the autocross committee, where applicable. Proposals for rules changes may be submitted to the committee for consideration at anytime, however, decisions on adoption may be deferred until the following season.
I. A. Eligible Entrants
PCA members in good standing, of any class of membership set forth in the by-laws, or nonmembers driving a Porsche, may register and compete in autocross events. Participants must be at least 18 years of age and have a valid driver's license.
Junior Participation Program
Children of PCA members who are fully licensed, unrestricted drivers, who have a completed parental permission form, and have signed the Minor Risk Acknowledgment form and are accompanied by their parent may participate.
I. B. Cars per Entrant
An entrant may drive more than one vehicle at an event provided that the second vehicle has been entered (fees paid), and passed tech inspection before registration closes. No points or trophies will be awarded for runs in the second car, and no entrant who drives a second car will get more runs than any other entrant in his/her run group.
I. C. Late Registration
Official registration and tech inspection will close as announced for each event. Late registration will be allowed only at the discretion of the Registrar, and late registrants will forfeit their morning runs.
I. D. Entry Fees
The cost per event for members and nonmembers, and the availability of a preregistration discount will be determined by the Northeast Region Board before the series starts each year and will be published in the NOR'EASTER. See Registration Info
IV. CLASSIFICATION
By defining the rules in this area, we are trying to afford all entrants the fairest possible competition while keeping a practical upper limit on the number of classes. It is the responsibility of each participant to classify his own car. If a model is not covered here, the participant must apply in a minimum of 1 week in advance for classification. Failure to do so may result in the car running unclassified for the event -or- may be classed at the discretion of the chair. A competitor in the same class may protest a car's classification, but must do so before the first competitive timed run. Conflicts over classification will be resolved via a Classification Committee appointed by the Event Chair. Their decision will be final, and may involve bumping a car into a more appropriate class.
Cars, for purposes of competition, are free to progress to higher classification level should they so choose. For example, should the driver of a street tire classed car wish to compete in the appropriate r-compound class, they are free to do so. However, this must be declared prior to the running of the event. Additionally, once a classification is chosen, if the car is co-driven, it must be done so under this classification.
A driver may be registered and participate in more than one vehicle for the event. However only one vehicle can be used for competition purposes and must be designated as the competition vehicle for the event prior to the event start. All runs taken in the non-competition vehicle are considered educational runs and will scored as a DNF. The total number of runs taken will not exceed the normal number of competitive runs for the event.

IV. B. Minimum CarsA minimum of one entrant shall constitute a class for any given event.
IV. C. Tire Classing
For cars in classes where an S/R designation must be determined, classification decided on the basis of the tire wear rating as specified on the sidewall of the tire. Cars equipped with tires displaying a wear rating greater than or equal to 140 are deemed to be in class S. Those tires with wear ratings below this number are deemed to be in class R. For cars other than class 10, all tires must be DOT approved. Any Porsche shod with non-DOT tires is automatically moved to class 10. DOT tires are free in classes 8 and 9. For classes 1-8 and 11S all free modifications are allowed regardless of tire choice. Cars with penalized modifications as per current rules are placed in class 9. As cars are permitted to run in a higher class, cars with S designated tires can elect to run in R on a seasonal basis. As stated elsewhere, cars are classified, not drivers. If a car is co-driven, it must run with a single class designation.
IV. D. Free Modifications
In this area we have tried to adopt a loosely interpreted, more lenient, version of the Parade Competition Rules (PCR's). This allows for various upgrades and replacement of troublesome items within a model range without bumping an entrant into a modified class.
Free modifications allowed in "stock" classes shall be as follows:
1. Changes within class (including engines and transmissions within model range, i.e. body style for
years sold in US).
2. Modified ignition and distributor
3. Cross bar supports on shock towers
4. Modified carburetor jets
5. Electric fuel pump
6. Wet sump modification
7. Modified oil cooler/filter
8. Engine rebuilds (cannot exceed factory tolerances and specifications).
9. Substituted chain tensioners/guards
10. Exhaust modifications after the head (not to include open exhaust)
11. Limited suspension modifications (no machining)
12. Substitution of coil springs, torsion bars, shocks, sway bars, coilovers
13. 356 Rear camber compensator
14. Any DOT wheel/tire combination fitting stock fender configuration (Subject to tire rules in Section IV.C. above)
15. Roll bars
16. Spoilers
17. Gear shift linkage
18. Limited slip differentials
19. Cross drilled rotors and/or competition brake pads
IV. E. Penalized Modifications
Cars which have one or more of the following modifications will be placed in the appropriate improved class unless it meets the criteria for the modified class. In this context "stock" is taken to mean components and configurations for the model and year which were/are readily available from Porsche as standard equipment or options as delivered through normal US dealers and intended primarily for street use:
1. Engine
a. Displacement increase from stock of more than 5%.
b. Compression ratio increase by more than 0.1 points.
c. Non-stock camshaft(s)
d. Head modifications beyond polishing (e.g., porting, oversize valves)
e. Turbo/supercharging if not originally so equipped.
f. (Turbo cars) Modifications increasing boost, including waste gate mods, chips, non-stock turbo
charger, etc.
g. Nitrous injection.
2. Drive train
a. Non-stock gear ratios (intermediate or final drive)
3. Suspension
a. Relocation of mounting points, including camber plates, etc.
b. Non-stock or modified components which alter the suspension geometry and/or allow
adjustment beyond that obtainable within the normal adjustment range.
c. Change of type (e.g., coil-over replacing torsion bar)
4. Body
a. Significant lightening by substitution of stock body panels or glass with lighter weight
components.
b. Significant lightening by removal of body components (e.g., bumpers).
c. Lightening by substantial gutting of interior components.
IV. F. Race
The Race class is for cars originally constructed or modified such that the primarily or sole intended use is racing and competition. A car will be placed in Race if any of the following criteria apply:
1. The car was originally constructed by the factory primarily or solely for racing/competition use.
2. The car is modified such that the primary or sole intended use is racing/competition. i.e., it is no
longer "streetable".
3. The car is running on non-DOT racing tires (e.g., racing slicks).
4. The car is unregistered or unregisterable for use on public roads.
Cars meeting one or more of the criteria for Race may be placed in an appropriate improved or stock class by appeal to the classification committee. The burden is on the entrant to show why the car should not run in Race. For example, an otherwise stock car which is unregistered and trailered to the event would be placed in the appropriate stock class. Committee decisions are final and apply for the remainder of the season, unless something has been changed which warrants reclassification.
Modifications not falling into any of the above categories shall be reviewed by the Classification Chair for suitability and safety. Decisions relative to those items, and classifications or reclassifications by reason of additional modifications, shall be made by the Classification Committee at its discretion.
V. SAFETY
All entrants are required to wear a helmet in good condition and seatbelts while driving in the events. Helmets with a safety rating of Snell 2000 or later are required. Both M and SA types are acceptable.
Roll bars are required for open cars in events termed "high speed"; this does not include Targa models. Boxster roll hoops are deemed adequate for "high-speed" events.
A three-point seat belt, with metal to metal fasteners, is required in all vehicles. Four-, five- or six-point harnesses are acceptable if properly installed as defined by the standards of the Driver Education program.
Tires must have visible tread with no cord showing. If cord shows no runs or further runs will be allowed until the problem is corrected.
No bare feet or sandals are permitted for while driving in the event.
Trucks, SUVs and vans are not allowed to compete in the non-Porsche class.
All cars must pass a tech inspection performed prior to the event. The purpose of this tech inspection is to perform a quick visual inspection of the major components including among other things, properly torqued wheels, tires in good condition showining no cording or cracking, battery firmly secured, wheel bearings tight, throttle not sticking, no loose object in the cockpit or trunks. This inspection is a cursory one performed by volunteers. It should in no way be construed as a professional appriasal of a competitors car and its worthiness to compete. All competitors are strongly encouraged to have their vehicle checked prior to an event by the qualified mechanic of their choice.
