Rules & Regulations

VINTAGE SPORTS 2000 NORTH AMERICA TECHNICAL AND SPORTING REGULATIONS

A. 1. Board of Directors
The Board of Directors of Vintage Sports 2000 North America (VS2) is comprised of an odd number of Directors between 3 and 7 as determined by a majority of the Board based on member interest in serving on the Board, among other factors. The Board will include a Director from each of VS2’s three regions (Northeast, Midwest, Southeast) and up to four at-large Directors. If no member from a region is willing to serve as that region’s Director, then that position will remain vacant until a regional Director is available. The Board may add regional Directors to reflect VS2’s changing membership. All Directors must be VS2 members and are elected by VS2’s membership for terms of two years each with elections held annually towards the end of each calendar year for half the seats. Directors are requested to notify VS2’s Chairman by November 1st if they wish to resign from the Board. A committee comprised of the Directors will canvass the members and nominate new candidates for election. A majority of Directors constitutes a quorum and Board votes are decided by simple majority. In the event of a tie vote the matter will go to the full Board for consideration. If there is an even number of Directors and the full Board splits about a matter that involves a material change to these Technical and Sporting Regulations or to VS2’s general operation, the matter must be approved by a majority vote of the members. If the matter does not involve a material change to these Technical and Sporting Regulations or to VS2’s general operation, the last retired Director will be asked to cast the deciding vote. The Board may appoint officers as it deems necessary.

A. 2. Committees
The Board will appoint a Technical Committee to advise and implement these Technical and Sporting Regulations, subject to Board review and approval. The Technical Committee will be the focal point for eligibility and technical inquiries. The Technical Committee serves at the pleasure of the Board. The Board may appoint other committees to advise or manage other functions in the interest of VS2’s membership. Committee members must be VS2 members but need not be Directors.

A. 3. Conditions of Registration
Competitors who wish to participate in the VS2 Series must hold a valid VMC-member club competition license or other license accepted by the sanctioning organization of each race event. All competitors shall abide by the terms and conditions contained in these Technical and Sporting regulations. The VS2 does not sanction races; it is an organization that conducts a points championship at events sanctioned by other organizers (VARAC, SVRA, HSR, VDCA, VRG, VSCDA, VARA, SCCA and others) and advocates for Sports 2000 racers at these events.

A. 4. Race series
The Board of Directors will develop an annual race series with a points paying schedule. Points will be awarded for races on the schedule and awards may be given at the discretion of the Board.

A. 5. Compliance and Penalties
Cars in competition must comply with the Technical and Sporting Regulations and any Technical Bulletins. Entry at an event means that the member driver attests to the legality of their car and willingness to present their car for inspection and verification, if requested, by the sanctioning organization and/or the VS2. Penalties can be membership probation and/or loss of points. Non-compliant cars will not be scored.

A. 6. Decals
VS2 and sponsor decals are required for a Member to be eligible to win sponsor awards. Cars must display the class designation for the car (see Section B.1.) and the applicable minimum weight required for the car with its driver (either 1,310 pounds or 1,335 pounds) based on its engine specification (see Section C.14). The class designation shall be displayed in a prominent location on both sides of the car so it is visible with the body work in place and the minimum height for designations shall be 4 inches with a 1 inch stroke. The minimum weight designation shall be displayed in a manner that makes it easily visible during technical inspection.

A. 7. Car Numbers
Car numbers are reserved for participating Members for one year on a first-come, first-served basis, priority being given to car owners who want to reserve the same number they raced the previous year. VS2 member numbers may not be the number the sanctioning body assigns the member for a particular race.

A. 8. Membership
A membership application is available on the VS2 web site.

B. Class Structure

B. 1. Classes
Sports 2000 (S2) cars include Lola T-87/90, T-88/90, T-90/90, T-91/90; Pratt & Miller; Shannon; Swift DB-5; Doran; Reynard; Carbir; Van Diemen, Shrike P16 and all Vintage and Historic class cars substantially modified beyond their original specifications.Vintage Sports 2000 (VS2) cars include: Apache; Lola T-594, T-596, T-598, T-86/90; Royale RP38, RP42; Shrike P15; Swift DB-2; Tiga SC85, SC86, SC87.Historic Sports 2000 (HS2) cars include: Aquila; Chevron; Crossle; Lola T-490, T-492, T-590, T-592, T-592S; March; Martin, MRC/81 (Mariah); Ocelot; Robinson; RoyaleS2000M, RP37; Tiga SC78, SC79, SC80, SC81, SC82, SC83, SC84.

B. 2. Modifications
Safety modifications, as required by a sanctioning body, are permitted and required. Determining the class of an upgraded car will be based on the later of either the chassis origin or the bodywork. For example, a Swift DB2 chassis with DB5 bodywork will be classed as a DB5 (see the Technical Bulletin page for information about acceptable DB2 tail specifications). Cars substantially updated or modified beyond their original specifications or with rear diffusers, horizontal protrusions on the bottom edge of the sides of the car (ankle cutters), or added vertical protrusions on the top sides of the car (fences) that did not originally use these aerodynamic devices will be classed in the S2 class.Members racing a car not in compliance with these Technical and Sporting Regulations will be notified by a VS2 representative of the non-compliant issue(s). Failure to correct any issue(s) by the member’s third race will make the car/member ineligible for VS2 points and points earned to date will be forfeited. Similarly, members racing a series of different non-compliant cars will be ineligible for VS2 points.

B. 3. Chassis and Suspension Improvements
Structural improvements to chassis and suspension components are permitted in the interest of safety.

B. 4. Changes to Regulations
Changes to these Technical and Sporting regulations will be evaluated and determined by the Technical Committee. The Technical Committee will report its decisions to the Board of Directors. Changes deemed significant by a majority of the Board will require membership approval by a majority vote of the members.

C. Preparation Rules

C. 1. Definition
Open cockpit two (2) seater rear engine sports racing car using a standard Ford 2000 cc single overhead camshaft “NE” series engine with a two-venturi carburetor.Sports 2000 is a restricted class. Therefore any allowable modifications, changes, or additions are as stated herein. There are no exceptions. IF IN DOUBT, DON’T.

C. 2. Safety Requirements
Note that the VS2 does not sanction races. Rather it is simply a points championship of events sanctioned by other organizers and serves as an advocate for owners of Sports 2000 race cars. Modifications for safety are required as specified in the regulations of the sanctioning body organizing each event. VS2 recommends the safety requirements of the SCCA.[/size]

C. 3. Chassis
Unrestricted except that the use of carbon fiber composite structural materials is prohibited. No engine oil or water tubes are permitted within the cockpit. The engine will be mounted upright and aligned fore and aft in the chassis.

VS2 recommends that Swift DB2 and DB5 cars have a properly installed crush box fixed to the foremost bulkhead to protect the driver’s feet. The box should meet the following requirements:
=12pxIt shall enclose a volume of at least 864 cubic inches (.5 cubic feet).

=12pxIt shall extend at least 10 inches forward of the front bulk- head.

=12pxIt shall be constructed of aluminum at least .040 inches thick, carbon fiber or Kevlar.

=12pxThe box may have access holes not exceeding 90 square inches in total.

=12px​All cars should have a longitudinal barrier in the left leg area forward of the dash substantially strong enough to prevent the left foot from moving more than 3 inches to the left of the vehicle centerline in the event of a side impact.

It is the intent of these rules to minimize the use of “ground effects” to achieve aerodynamic down force on the vehicle. Thus, the chassis and body surfaces that comprise the underside of the car shall not deviate from a flat plane by more than 2.5cm (one (l) inch). This deviation may not be used to create an aerodynamic device. For this purpose the underside is defined as being within the rectangular area along the length between the front edge of the front wheels and the rear edge of the rear wheels and across the outside of the front and rear rims. No aerodynamic devices (e.g. “skirts,” body sides, etc.) shall extend below this surface anywhere on the car to the rear of the front wheels.

​C. 4. Bodywork Including Airfoils

a. The body shall provide a cockpit for two (2) seats and cover all mechanical components including wheels and suspension members except for the exhaust pipe, induction system, and camshaft cover which may protrude through the engine cover.
b. Between the front and rear axle lines the body shall:
1. Maintain over a minimum of 70% of the length of the wheel- base and over a depth of 20cm (7.9 inches) a minimum body width exceeding the greatest overall width across the tires less 15cm (5.9 inches).
2. Exceed in height the top of the tires over a width of 50cm (19.7 inches) excepting only cockpit and engine openings. There shall be no gap between the main body and the mudguards. The mudguards shall cover the full width of the tires around an arc of 120 degrees, which shall extend forward ahead of the axle centerline on the front and rear wheels and behind the rear wheels to at least 7.5cm (2.95 inches) above the axle center- line.
c. Maximum vehicle length forward of the front axle centerline: thirty- three (33) inches. Maximum vehicle length rear of the axle center- line: thirty-seven (37) inches.
d. The body above chassis level in the region of the cockpit shall not be reinforced in any way, which would complicate or hinder the rescue of the driver. The cockpit opening seen in plan view shall be symmetrical about the longitudinal axis of the car and shall be large enough for a horizontal rectangle of 80cm (31.5 inches) by 40cm (15.75 inches) to be passed through with its minor axis aligned with the vehicle’s longitudinal axis.
e. Space for two (2) seats shall be provided, each of at least 40cm (15.75 inches) width, and shall be positioned symmetrically about the vehicle’s longitudinal axis. There shall be at least 25cm (9.9 inches) wide foot space for both driver and passenger measured at the pedals. The passenger space should provide as much seat space, elbowroom, foot, and legroom in terms of length, width, and height as that of the driver. Battery boxes and fire systems are permitted in the passenger seat area.
f. Maximum height with driver on board, excluding safety rollover bar and mirrors, shall not exceed at any time 90cm (35.4 inches) measured from the ground.
g. Airfoils and/or spoilers mounted at the front of the vehicle are permitted. These airfoils and/or spoilers may only be adjusted in a horizontal plane.

E. Driver Conduct and Safety

E. 1. VS2’s Objectives
VS2’s objective is to promote the preservation and enjoyment of Sports 2000 cars in a racing venue emphasizing driver safety and etiquette. Racing is an inherently dangerous sport. The proper attitude of the driver is integral in reducing risk and enhancing our Member’s appreciation of the sport.

E. 2. Rules of the Road.
a. VS2’s goal is to support the sanctioning organization’s desire to operate a safe event. By emphasizing rules of conduct, we all know how we are expected handle on track decisions.
b. Driver attitude: It is important to understand how vintage and historic racing is different from other forms of auto racing. Race groups often include cars that have very different speed potentials. Even when lap times are similar, one car may be much quicker down the straights while another may be able to brake later or carry more cornering speed. The result is that two cars may seem to be in each others way often. Run groups often have very experienced drivers racing at 9/10 in fast cars mixed with drivers with limited experience driving cars with less speed potential, happy to be driving at 7/10. Such is the nature of vintage and historic racing. This means the Member driver must understand and accept these differences and be willing to adjust their driving to accommodate all drivers and cars.
​c. Overtaking: It is the responsibility of the overtaking car to plan, execute and complete a safe pass. The car being passed has the right of way until the pass is completed safely. Despite the passing flag (blue w/ yellow diagonal) being shown to a slower car, that slower car is not required to yield the line through a turn. If the passing car is clearly ahead of the overtaken car at or before the turn in point, the passing car must not compromise the safety of the overtaken car. The overtaken car may yield the apex, but the overtaking car must not push the overtaken car off the road. You have not completed a pass until the rear of your car is in front of the car being passed. Only then, have you fulfilled responsibly a safe, clean pass.[/size]

Being overtaken: All drivers have a responsibility to keep an eye on their mirrors. You must be aware of the cars that maybe be about to pass you. If the car behind you is clearly a faster car, or you simply desire the car to pass you, point to the side you want to be passed on. This is best done as you exit a corner. That point-by is valid until you reach the turn in point for the next corner. When you give a point-by, stay on your normal line. The only exception is when you give a point by as you are approaching a corner. In that case, you are indicating that you will share the turn with the overtaking car. You MUST then leave room for the faster car to make a pass by sharing the corner with them.

d. In-traffic: When in heavy traffic typical of the first few laps, it is imperative that you not make any rapid line changes without first being sure that you are not going move into the path of another car or cause contact between cars.

Blocking: When racing for position with another car, you may not make more than one lateral move. You must not intentionally or repeatedly deprive the other car racing room. You must not make sudden, unpredictable moves off your normal line to “shut the door” on the other car.

Damage avoidance: If a car ahead loses control, you should treat this as an automatic waving yellow. The cars in front of you may slow to avoid contact. Do not pass. When you get past the car in trouble, you may resume racing[size=120]

D.1 NAC-SRCC Technical Bulletin #1 – January 25, 2005[/size]

Swift DB-2 Bodywork:

The NAC-SRCC Technical Committee has been asked to clarify the proper configuration and dimensions of the legal and desired DB-2 bodywork, specifically the tail.

While the top overall length dimension, including the integral spoiler on the DB-5 tail, is identical to the top overall length dimension, including the detachable “duckbill” extension on the DB-2, it is mandatory that the top dimension of any car presented, under no circumstance, be more than 74″ long. The side dimensions of the tail in NAC-SRCC-legal configuration are required to be the dimensions shown in Figure 2. The “duckbill,” while preferably detachable as original, must be no larger than the dimensions in Figure 3. The duckbill is available for sale from Motorsports Composites in Wisconsin for a reasonable price. The duckbill may be made of fiberglass or aluminum and must have a wicker mounted on a vertical plane at the rearmost point on the duckbill.

It is possible to reduce the side length of a DB-5 tail to the dimension in Figure 2 and attach a duckbill not exceeding the dimensions in Figure 3 for use in the NAC-SRCC series. Remember, our goal is to present the cars in their most historically accurate form – specifically as they were raced before the December 31, 1986 eligibility cut-off date.
