 SCCA SPORTS RACING CATEGORY PREPARATION RULES

The SCCA Sports Racing Category shall be for automobiles which are designed and constructed for road racing competition, offering provisions for driver and a passenger, or driver alone (single-seater). They shall conform to the following requirements.

New chassis of non-metallic composite construction shall be proven to meet FIA specifications for non-metallic composite chassis prior to being submitted to the SCCA for homologation. Contact the SCCA national office for a list of the relevant FIA specifications/SCCA requirements.

Effective 1/1/97, those cars formerly known as Sports Renault and/or Spec Racers or any variants of this chassis/drive train/bodywork combination will not be allowed to compete in ASR in any SCCA sanctioned event.

Single‑seat Formula car chassis (Ex.: FA, FC, FF, FV) fitted with enclosed bodies (as specified in these rules) may run in the Sports Racing Class (ASR, CSR, DSR) appropriate for their engine displacement and GCR Section 9. This means that all Formula Atlantic, Formula Continental, Formula F, and Formula Vees running in Sports Racing categories shall have bodywork which complies with Section A.1 or A.2, of the Sports Racing Specifications. The ex‑Formula car chassis need not have any former engine(s) fitted. Converted cars will maintain their former SCCA registration vehicle numbers. Each converted car shall be Homologated and have a new Vehicle Logbook (with new pictures); however, the former Logbook will be securely attached to the new Logbook. This procedure will enable Race Officials and Scrutineers to identify a single‑seat Sports Racer as formerly having been a bona fide Formula car. New Single seat Sports Racers may be of new construction. (Design plans/pictures shall be submitted to Club Racing Technical Services for homologation before competing.)

Where Weber or other approved carburetors are specified and used, they shall retain their standard configurations of fuel distribution. This is to prohibit annular discharge carburetors.

It is the intention of the Club Racing Board to never classify or replica or derivative of a mass produced road car body in the sports racing classes.

These classes are intended for open and/or closed sports racer/sports prototype bodywork

Sports racing cars shall be classified according to engine displacement and divided into classes as follows:

• A Sports Racing (ASR) - Regional Status Only (Former Can-Am and F-5000 allowed if registered prior to 01/01/2003)

• C Sports Racing (CSR)

• D Sports Racing (DSR)

• Sports 2000 (S2)

• Spec Racer Ford (SRF)

BASIC DESIGN CONSIDERATIONS

1. All portions of the roll cage subject to contact by the driver must be padded with a minimum 1 inch of material. Padding that meets or exceeds SFI 45.1 or FIA 8857-2001 (curved padding), or SFI 45.2 or FIA sports car head rest material (flat padding) specification is recommended.

2. No portion of the roll cage may have an aerodynamic effect by creating a vertical force.

3. The radius of all bends in the roll cage (measured at centerline  of tubing) must not be less than 3 times the diameter of the tubing.

4. It is recommended that all joints of the roll cage be welded. All welding must include full penetration, no cold lap, no surface porosity, no crater porosity, no cracks, no whiskers, and so forth. Welds shall be continuous around the entire tubular structure. Alloy steel must be normalized after welding. It is recommended that a certified AWS D1.1 welder do all welding.

5. It is recommended that gussets be used at all joints. In Improved Touring, Showroom Stock, and Spec Miata a maximum of 2 gussets per joint are allowed and must be no thicker than .125”.

6. Any number of additional tube elements is permitted within the boundaries of the minimum cage structure. Such tube elements may pass through any mandatory or optional bulkhead or panel separating the driver/passenger compartment from the trunk/cargo area/fuel tank/fuel cell area provided the bulkhead is sealed around such tube elements.

9.4.5. ROLL CAGES FOR FORMULA CARS AND SPORTS RACING CARS

All Formula and Sports Racing automobiles are required to have full roll cages. Cage may be of two designs, low front hoop (top of steering wheel) or high front hoop (equal to rear hoop) but with no diagonal brace.

2 seat Sports Racing cars shall have full cockpit width cages. 

 All tube frame automobiles shall have both front and rear hoops formed of tubing per 9.4.5.E.4. On automobiles of full monocoque construction, a fabricated sheet metal front hoop structure may be approved upon specific application to the SCCA.

 Closed cockpit Sports Racing car cages may be constructed in accordance with 9.4 ROLL CAGES FOR GT AND PRODUCTION BASED CARS.

All Formula car and Sports Racing car roll cage tubing specifications must meet the current GCR specifications, effective 1/1/98.

A. Main Hoop

The main hoop shall be constructed of tubing per 9.4.5.E.4. The minimum bend radius shall not be less than 3 times the tube diameter measured from the tube centerline.

The main hoop shall not be less than 2 inches above the driver's helmet, seated normally and restrained by seat belt/shoulder harness. A straight line drawn from the top of the main hoop to the top of the front hoop shall pass over the driver's helmet. On Formula cars and single seat Sports Racing cars the vertical members of the main hoop shall not be less than 15 inches apart (inside dimension) at their attachment to the chassis. If the hoop does not go to the belly pan, proper gussets and tube triangulation shall be used under its attachment.

On monocoque chassis the main hoop shall be welded to mounting plates not less than .080” thick. It is important that these plates be attached to the chassis in such a way as to spread the loads over a wide area. There shall be a plate of equal thickness on the inside of the monocoque with solid rivets or bolts (5/16” minimum bolt diameter) through the non-ferrous material.

B. Front Hoop

Low front hoops must be no lower than the top of the steering wheel. It is recommended the hoop extend to the belly pan. If not, it shall be attached to the chassis with gussets and triangulation in order to spread the loads. In automobiles of full height (top of the steering wheel) monocoque or composite construction, a steel cap plate, not less than .080” thick must be attached as a rub block.

C. Roll Cage Bracing

1. The main hoop must have 2 forward braces extending from the hoop and attached to the frame, monocoque, or front hoop. Braces must be attached as near as possible to the top of the hoop but must not be more than 6 inches below the top and at an included angle of at least 30 degrees.

  If these braces do not extend to the front hoop, an additional brace or gusset (14 gauge - .078” minimum thickness) must be installed between the lower frame rail and the upper frame rail at the point of attachment of the forward hoop brace. If these braces do not extend to the front hoop, an additional brace or gusset must be installed at the point of attachment to the main rear hoop or lower frame rail or other major frame member in such a manner as to reinforce the attachment point to help prevent collapse of the frame rail at the point of attachment. These tubes shall be 1” x .080” minimum and gussets shall be 14 gauge - .078”minimum thickness.

    2  seat Sports Racing cars with full width main hoops must incorporate a lateral brace to prevent lateral distortion of the hoop (See figure 12). All bracing on full width cages must be the same diameter and wall thickness as the main hoop.

   Formula and single seat Sports Racing cars under 1500 lbs., may use bracing with a minimum dimension of 1.0” diameter by .080” wall thickness.  

  Braces attached to monocoque chassis must be welded to plates not less than .080” thick and backed up on the inner side by plates of equal thickness using bolts of Grade 5 or better with 5/16” minimum diameter.

2. The front hoop must have 2 braces near its top extending forward to protect the driver’s legs. It is recommended that this bracing extend to the bulkhead in front of the driver's feet; but in any case it must be integrated into the chassis to provide substantial support for the front hoop. Full width front hoop bracing shall be a minimum dimension of 1.0” diameter by .080” wall thickness tubing. Formula and single seat Sports Racing cars under 1500 lbs., may use tubing with a minimum dimension of 1.0” diameter by .080” wall thickness. When monocoque construction is used as bracing for the front hoop, it must be approved on an individual basis. If a high front hoop is used, it must be similar in shape to the rear hoop and have two horizontal tubes connecting the top of the front hoop to the top of the main hoop. The bracing for the main hoop remains the same.

3. Removable bracing must incorporate connectors of the doublelug, tapered, or muff-type as shown in figures 14, and 15. The double-lug type must include a doubler, gusset, or capping arrangement so as to avoid distortion or excessive strain caused by welding.

D. Composite Chassis Safety Structures

1. The basic purpose of safety structures is to protect the driver.

This purpose is the primary design consideration.

2. All cars must have at least 2 roll over structures, but the use of titanium is prohibited.

The first roll over structure must be in front of the steering wheel, not more than 25cm forward of the steering wheel rim, and at least as high as the top of the steering wheel rim. The second roll over structure must not be less than 50cm behind the first. It must be high enough for a line extending from the top of the front structure to the top of the rear structure to pass over the driver’s helmet when he is seated normally in the car with his helmet on and the seat belt fastened. This second structure behind the seat must be symmetrical about the lengthwise centerline of the car and comply with the following dimensions: The top of the roll bar must be at least 2 inches (5cm) above the driver’s helmet when the driver is seated in a normal driving position. No second roll structure on a composite chassis will be considered unless it contains a main hoop having a minimum tubing size of 1.375” x .080" wall thickness. Supplemental braces must have a minimum tubing size of 1.00” x .080” wall thickness.

The roll bar must be capable of withstanding the following stress loading applied simultaneously to the top of the roll bar: 1.5 (X) laterally

5.5 (X) longitudinally in either direction

7.5 (X) vertically

where (X) = the minimum weight of the car.

   The induced loads must be carried over into the primary structure of the chassis. The ability of the roll bar to bear and distribute the load through the chassis must be demonstrated satisfactorily in test conditions to the SCCA.

   In conjunction with SCCA, manufacturers of cars utilizing carbon fiber composite survival cell construction will be required to designate repair locations capable of proper evaluation and damage repair. In the event of damage to the chassis, repairs can only be made at these locations. Proper documentation must be made in the vehicle logbook. No car will be allowed to compete after damage without following this procedure.

E. Basic Design Considerations

1. The basic purpose of the roll cage is to protect the driver if the car turns over, runs into an obstacle such as a guardrail or catch fence, or is struck by another car. It shall be designed to withstand compression forces from the weight of the car coming down on the rollover structure and to take fore/aft and lateral loads resulting from the car skidding along on its rollover structure.

2. No portion of the safety roll cage shall have an aerodynamic effect by creating a vertical thrust.

3. Roll cage or chassis design shall prevent engine intrusion into the driver compartment.

4. Material:

  a. Seamless, or DOM (Drawn Over Mandrel) mild steel tubing (SAE 1010, 1020, 1025) or equivalent, or alloy steel tubing (SAE, 4130) shall be used for all roll cage structures.

Proof of use of alloy steel is the responsibility of the entrant.

  b. Minimum tubing sizes for all required roll cage elements (All dimensions in inches):

Vehicle Weight Tubing Size (inches) With Driver (outer diameter x wall thickness)

Up to 1700 lbs. 1.375 x 0.080

1701-2699 lbs. 1.50 x 0.095 or 1.625 x 0.080

Over 2699 lbs. 1.625 x 0.120 or 1.75 x 0.095

  c. For purposes of determining tubing sizes, the vehicle weight is as raced without fuel and driver. The minus tolerance for wall thickness should not be less than .010” below the nominal thickness.

  d. Either an inspection hole at least 3/16 inch diameter, but no greater than 1/4 inch diameter shall be drilled in a non-critical area of the front and rear hoop as well as the one of the supplemental braces to facilitate verification of wall thickness; or alternatively, wall thickness may be determined by non-invasive means and noted in the log book as inspected by such means. Formula Cars and Sports Racing cars with alternate roll structures are not required to have inspection holes, the wall thickness will be indicated on the back of the homologation certificate.

5. One continuous length of tubing shall be used for the main hoop member with smooth continuous bends and no evidence of crimping or wall failure. The radius of bends in the roll cage hoop (measured at centerline of tubing) shall not be less than 3 times the diameter of the tubing. Whenever possible, the roll cage hoop should start from the floor of the car, and, in the case of tube frame construction, be attached to the chassis tubes by means of gussets or sheet metal webs with support tubes beneath the joints to distribute the loads. It is recommended that gussets be used.

6. Welding shall conform to American Welding Society D1.1:2002, Structural Welding Code, Steel Chapter 10, Tubular Structures.

Whenever D1.1 refers to “the Engineer” this shall be interpreted to be the owner of the vehicle. Welds shall be continuous around the entire tubular structure. All welds shall be visually inspected and shall be acceptable if the following conditions are satisfied:

a. The weld shall have no cracks.

b. Thorough fusion shall exist between weld metal and base metal.

c. All craters shall be filled to the cross section of the weld.

d. Undercut shall be no more than 0.01 inch deep.

7. Aluminum bronze or silicon bronze welding technique is permitted, but extreme care shall be used in preparation of parts before bronze welding and in the design of the attaching joints.

8. Forward braces and portions of the main hoop subject to contact by the driver's helmet (as seated normally and restrained by seatbelt/shoulder harness) shall be padded with a non-resilient material with a minimum thickness of 1/2 inch. Padding meeting SFI spec 45.1 or FIA 8857-2001 is strongly recommended.

9. Cars may compete with FIA homologated cages provided the cage was built by the manufacturer or a manufacturer-designated shop/team and approved for use.

F. Exceptions for Formula Cars and Sports Racing cars Any roll hoop design which does not comply with the specifications in

9.4.5, will only be considered if it is accompanied by engineering specifications signed by a registered engineer. No alternate roll hoop will be considered unless it contains a main hoop having a minimum tubing size of 1.375” x .080” wall thickness. The roll bar must be capable of withstanding the following stress loading applied simultaneously to the top of the roll bar: 1.5 (X) laterally, 5.5 (X) longitudinally in both the fore and aft directions, and 7.5 (X) vertically, where (X) = the minimum weight of the car.

G. Front Impact Attenuation

1. All formula cars registered or homologated with SCCA as of 1/1/1986 must have a front impact attenuation device meeting at least one of the following criteria:

A. An FIA-approved front impact attenuation structure.

B. A metallic structure, securely attached to the front bulk head, with a minimum cross section of 200 sq cm (31 sq in.), 40 cm (15.75 in.) forward of the clutch and brake pedals (not depressed), constructed of a minimum of 18 gauge 6061-T4 or equivalent aluminum.

C. A non-metallic composite structure, securely attached to the front bulkhead or incorporated into the nose piece, with a minimum cross section of 200 sq cm (31 sq. in.), 40 cm (15.75 in.) forward of the clutch and brake pedals (not depressed), constructed of a minimum of 6 mm stabilized (e.g., honeycomb) material with inner and outer reinforcements of a minimum of 2 5-ounce laminate material (fiberglass, carbon, Kevlar, and so on).

2. Formula Vee and other formula cars using the VW sedan H-beam front suspension must satisfy the requirements of section 9.1.1.C.3.A.10 or use any of the structures listed in 9.4.5.G.1.

3. Formula Mazda cars may use the spec front wing support as a front crush structure, or any of the structures listed in G.1 above.

4. Radiators may be incorporated in impact attenuation structures.

5. Composite impact attenuation structures may incorporate carbon and/or kevlar regardless of any class restrictions on materials.

6. Rear impact attenuation structures are strongly recommended for all formula cars, and may incorporate the materials and/or construction techniques listed above for front impact attenuation structures.

7. Pre-1986 formula cars and all Sports Racing cars are strongly urged to use front and rear impact attenuation structures, and may incorporate the materials and/or construction techniques for front impact attenuation structures listed above.

Big, 1 3/4" Tube, Sports Racer

This is very close to how the 6 Wheeler Chassis will look

  The Basic Chassis Structure of the 1 3/4" Tube

The Fuel Cell will be in the Truss Area Bulk Head Behind the Seat. It's the 10 Gallon Fuel Safe # SM110 or FF110.

There will not be a Fuel Cell Aft of the Main Hoop, as this Chassis has.

The Center section will be about 2" longer & is the same exact width.

The Rear Rims & Tires are any size or width, 1 piece rims including the 4 on 100 Miata Rear for the Bike Motor chain Drive.

The 4 Front Rims will be 8" max width & 225-45-15 Tires

 

 

This is the 1000cc Closed Cockpit
 
The Closed Cockpit Cars will look somewhat like this.
















Above is the First Closed Cockpit, the Side Bars are Now Lower at the Main Hoop.


Chassis Build Out 

The Front, Miata Suspension, Axel Center Line can be up to 2" Aft of the Front Face of the Foot Box Bulk Head and it, shall be a minimum of 18" Wide by 12" High, also the bottom of the front Horizontal Foot Box Tube may be up to 6 1/2" above the flat reference plane (the flat bottom chassis tubes).


This Foot Box bulkhead Shown below, is raised 5" above the flat reference plane & the lower suspension bolts are about 7 1/4" above.




   Above is Miata Lower Front Suspension Mounts, they use the OEM Cam Bolts to mount the Lower A-Arms. This 8 piece kit is 1/8" plate, they are oversize, you'll cut to size.

Note: The lower A-Arm mounts should be .120 or 1/8" Steel





Above is OEM Miata Front Suspension, This was pulled from a salvage yard and the total cost was $80 for the right & left sides.

 

 
 Front Big Brakes for the 2800cc  $635 Plain & $750 Drilled
95 to 2000 Miata Kit 140-11704  Call (805) 388-1188

 Front A-Arm Bushing Kit  11.3105R $52.   12-204  $34.

MA-1110-BL  Techna-Fit Brake Lines    $97.50

Developing the New Front Suspension
The Plane Angle is 45 degrees, It will be very Adjustable.
The next "Bell Cranks" will be Machined, just seeing how well they work & what changes need to be made.  I'm not going with this, it may work but the Aero is dumber than Obama's ears.
