This page contains operating rules, classes, and general information. Please review and download important documents such as the tech form.
Remember, as of 2015: all Stock and Production cars, and this means 90% of you, must have tires with a wear rating of 140 or greater.
NNJR Autocross Operating Rules 2015/16
- Each driver must wear an “M” or “SA” rated helmet carrying a 2010 or later Snell Memorial Foundation approval sticker. For those purchasing a new helmet, a 2010/15 “SA” rated helmet is strongly recommended, but an “M” rated helmet is acceptable. Loaner helmets are available for new drivers. You MUST purchase a balaclava (disposable liner) to borrow a helmet.
- All NNJR Autocross events are FULLY MUFFLED EVENTS. Any car having a noisy exhaust system will be rejected.
- Metal-to-metal seat belts, securely anchored are required. 1965-68 “900 Series” cars must modify the outer seat belt anchors so that the belt crosses the pelvic bone and lower abdomen and down toward the anchor point as near to a 45 degree angle as possible.
- Sneakers, tennis shoes or other rubber-soled shoes are recommended. High-heels, sandals and the like will not be allowed.
- Roll Bars are recommended for all open cars.
- Fire Extinguishers are not mandatory but recommended. For those cars equipped with fire extinguishers, the extinguisher must be a minimum of 2.5 pounds, BC or ABC rated and fully charged. It must be fastened to metal using metal brackets and fasteners, within reach of the driver while buckled in the driver’s seat.
- Tire and wheel combinations must be completely covered by the bodywork and have sufficient clearance to prevent rubbing that could be considered to be dangerous.
- You must retain a Porsche OEM engine block or case (except for X class).
- All drivers must read, print and sign the tech form (available on the documents page). All cars must pass an on-site safety inspection. All loose articles must be removed prior to the safety inspection. Having the car inspected is the responsibility of the driver. A car that has not been inspected will not be allowed to compete. Late inspections are at the convenience of the Tech Inspectors.
- Cars /drivers not following the series rules will be subject to protest. Protests which are upheld may result in disqualification from the event, reclassification or other changes as determined by the event chairperson.
- A driver may only enter one (1) car in an event. A maximum of two (2) drivers are allowed per car. Co-drivers of the same car may be asked to run in opposite heats.
- In accordance with New Jersey law, absolutely no passengers are allowed at any time, except for pre-approved NNJR instructors. If an instructor drives your car for a run, the time will not count, and you will receive a re-run.
- All rules are the same for Novice and Veteran classes, except for tires (see below). New autocrossers with fewer than three (3) events of experience will have an instructor provided (mandatory) for their first run of the day. Instruction is available (and encouraged!) for all participants throughout the event.
- All drivers must have a work assignment at a flagging station or other duty assigned. Any driver who does not show up for their work assignment may not be allowed to drive, or may forfeit championship points, at the discretion of the event chairperson.
- NO ALCOHOLIC BEVERAGES OF ANY TYPE MAY BE CONSUMED BY ANY PERSON DURING THE DRIVING EVENT. THE USE OF ANY ILLEGAL OR REFLEX AFFECTING DRUGS IS STRICTLY PROHIBITED.
NNJR’s 2015/16 Classing Worksheet is here:
General Overview of Class Structure
NNJR Follows the National PCA PCR’s for Medium Size Regions. Cars are placed into classes so that cars of approximately the same capabilities compete with each other. In addition, Novices (see below for definition) run in separate classes from veterans. Men run in the “Open Class”. Women may elect to run in either the “Ladies Class” or the “Open Class”.
Classes carry a “PAX” which is a form of handicap and allows drivers in two classes to compare runs more fairly – e.g.: faster cars are proportionally adjusted compared to slower cars by a percentage (e.g.: time x 0.95 for a faster car vs time x 0.9 for a slower car).
NNJR has an open policy to encourage participation by our friends, family members and SCCA competitors who do not drive Porsches. We call this “X” class and is open to any brand car that meets our safety requirements. We even give a trophy for the fastest X class competitor.
Open Classes will compete against other cars in their respective classes. (i.e. S5 competes against other S5 cars). S Classes, P Classes, Ladies Classes, and Rookie Classes will be “paxed classes” where all of the participants (in this case, all rookies, ladies, or showroom stock cars) run against each other regardless of car classification, with their scores handicapped by their car type. These handicap factors are called “pax” factors. The paxes to be used for the season are shown in the rules section. (i.e. S1 competes against S1, etc., with factors applied to the raw times for handicapping)
Stock is designed for cars with no modifications. The NNJR classification philosophy is for Stock classes to only allow minor changes, of the type commonly made by performance-minded Porsche owners. Improved classes are designed primarily for cars with significantly improved suspensions. The Modified class is for cars with significant changes, such as lightweight bodywork modifications and engine swaps. Modified cars must maintain the same levels of essential equipment as a “street” car, however including headlights, taillights, turn signals, a windshield and all glass (Lexan or similar is acceptable as replacement as long as it is clear), body panels (original or replacement)
X Class cars will be classed and paxed according to current SCCA Class and Pax Classifications and posted on the NNJR website. No changes may be made to cars in Stock, Improved, or Modified classes, unless authorized below. R Class is limited only to the fact that the car must have a Porsche engine block and chassis.
Mis-classification can be protested. Use or deletion of any equipment not covered in these rules that, in the opinion of the Event Chairperson, results in increased performance will move the car into the next higher class (Improved or Modified). PROPER CLASSIFICATION IS THE RESPONSIBILITY OF THE ENTRANT.
There are four categories of classes – Showroom Stock, Production, Improved and Modified. Categories are related to automobile configuration.
The Showroom Stock (S) Category contains classes of automobiles as normally delivered and specified for use in the United States and Canada. Factory options as normally available for a specific model year are permitted. Certain factory and/or dealer installed equipment/ options will move an automobile out of S and into Production or higher as specified in the Modifications Allowed List table so as to maintain the intent and integrity of the Showroom Stock classes.
The Production (P) Category contains automobiles (as normally delivered to the United States and Canadian public through authorized sales outlets of the manufacturer) plus others with limited performance-affecting changes from stock. The Improved (I) category contains automobiles with more substantial performance-affecting changes from standard (stock) specification, whether changed by the factory, dealer or owner. These modifications have defined limits. These automobiles are classed according to their number of cylinders and actual displacement.
The Modified (M) Category contains automobiles that have performance-affecting modifications outside of the limits of the Improved category and for race automobiles (factory-built or otherwise). These automobiles are classed according to their specified number of cylinders and actual displacement.
