Subject: SMRS Rules and Reg Update

I wanted to pass along the latest on Sprite Midget Race Series Rules and Regulation revision 5/16/23, which you can see below or it maybe clearer in above attachment.  This has been reviewed by the majority of Rules and Reg Team.  Yellow highlights latest changes

2023 VSCDA Sprite Midget Race Series Rules and Regulations
(Revision 5/16/23 rough draft)
I. Objective: Increase numbers for Racing Spridgets @ VSCDA Events by having:
A. More cars, which, will allow more wheel to wheel racing safely within Spridget Classes (with classes for various levels of preparation).
B. Continued tradition established by Thickos through camaraderie and group get together (cook out lunch Saturday and Sunday, British Pub Saturday evening when a 3 day race weekend along with technical and moral support through group).
C. Series Points developed from Earlier Vintage Vee model. Including durability (laps completed) from 1st Sprint Race, Fastest time from 1st Qualification Race and Position for Spridget Race in a best 2 out of 4 race weekends identified in series.
D. To embrace vintage sports car racing philosophy and etiquette of VSCDA’s Driver Policy with an emphasis on Safety.
E. Encourage street Austin Healeys & MGs as spectators by offering special parking near our Spridget Compound inviting them to join in the fun and encourage track touring session and assisting as crew.
Note: Revisions to this document will be highlighted in yellow so changes from previous documents can be seen more easily. Date of revision will be listed at top of document. II. 2021
II. VSCDA Sprite Midget Point Races 2023:
A. Gingerman April 4-28 – (May 4&5 Driver School) (May 6&7 Race Weekend)
B. Blackhawk Classic June 16-18
C. Waterford Hills July 21-23 near Clarkston, MI
D. Grattan Grand Finale August 11-13
III. Racing Classes per VSCDA / SCCA (1972 Classifications Guidelines for Points and Awards) Revamp with 1972 GCR / PCS Focus. Our intent is to have anyone interested in racing a Vintage Spridget to join us. This is a double edge sword since an individual may have their own personal opinion of why they think they should or should not be in a certain class. Vintage Racing has many clubs throughout the US and Canada with different criteria than ours. We have 3 levels within 3 classes that should allow anyone interested in racing to have a place to compete with other similar prepared racing Spridgets. We recognize that everyone has an opinion of what is fair, based on their logic. We have tried to make that more defined by 1972 SCCA GCR Specifications detailed, which is a VSCDA requirement. We would like to encourage placing the proper designation on your car & when you register.
IV. SMRS 1972 SCCA GCR / PCS Highlight of Requirements.
A. Background: VSCDA defines Regulations for Group 2 cars like our Sprites and Midgets from the VSCDA Website and updated 3/28/22 titled TECHNICAL REQUIREMENTS FOR RACE CARS:
B. VSCDA - SCCA 1967 General Competition Rules Appendix A/Article. Production Category Sports Cars (w/PCS sheets) and after review, 1972 and prior cars homologated to similar regulations published by FIA and some other sanctioning bodies.
C. Objective: Now that we have a copy of SCCA’s 1972 GCR /PCS rev 1/73 we actually have facts on what was required then vs what we heard or thought it might be. This document is available to anyone that would like an electronic copy. The goal for this document is to highlight requirements as of 1972 GCR that would impact Square Body Sprites and Midgets on common areas of misunderstanding. For the sake of commonality and consensus within our group Mk1 Bug Eyes will also follow 1972 GCR requirements, which is consistent with VSCDA requirements.
D. 1972 SCCA GCR Highlights (the following highlights are for those wanting to run in ERA Correct 2E Bug Eye or 2D Square Body class). Comments are in ( ) for clarification:
a. Interior:
                i. Instrument panel (maybe altered if weight is not reduced see GCR)
ii. Interior trim – Removal of interior trim except door panels
iii. Seats – Driver seat maybe replaced. Passenger seat maybe removed.
b. Exterior:
i. Grills may not be removed
ii. Front signal light, lenses, bulbs must be removed and opening can be used for venting brakes with maximum ¼ in wire mesh
iii. Headlight openings must be covered if not used for ducting air and must be metal, fiberglass etc.
iv. Spoilers are permissible, but minimal (see additional details 1972 GCR)
v. Fenders maybe altered only to provide for tire clearance, provided that the fender opening profile, viewed from the side of the automobile is not changed. vi. Safety fuel tanks must be place close to original position.
c. Tires, Wheels, Suspension:
i. Wheels maybe 1.5 inches wider than specified. Wheels may not exceed +/- 2 inches track dimension. Center lock wheels and hubs is permitted within this track restriction (wire wheel condition), (square bodied cars in the later years had 4.5 inch wide rims so up to 6 inch wide rim is possible)
d. Engine Compartment:
i. Battery – make or size of battery provided its voltage and location remains unchanged
ii. Generator / Alternator – Standard maybe replaced with generator or alternator of different make or size as long as location and drive are the same. iii. Velocity stack and or cold air box maybe used
iv. Transmission / Rear Axle – ratios as specified by SCCA (PCS) Straight Cut Close Ratio accepted with designated ratios (these ratios were BMC’s Straight Cut Close Ratios)

VI. Race Series Points 2022 awarded from accumulation of 2 of the 4 designated races of Gingerman, Black Hawk Farms, Pittsburgh GP and Grattan.
A. 1st Sprint Race (Durability Points per class) represent 1/3 of total points during race weekend. The First Sprint Race is usually held on Saturday (maximum 8 points). If a racer completes less than the most completed laps available by a similar class racer the results will be based on a percentage of that 8 points rounded up.  These points reward endurance. If the class session has less than 8 laps and a competitor completed all laps available they will be awarded 8 points.
B. 1st Qualification (Fastest Time per class): Points are awarded per C below except based on fastest time.
C. Sprite Midget Exclusive Race (Finishing Position per class): Points are awarded based on finishing position. First (8 points), Second (7), Third (6), Fourth (5), Fifth (4), Sixth (3), Seventh (2) & all other finishers (1).
D. A racer can accumulate up to 16 points for Qualification and Sprint Race along with additional points for the Feature Race or Exclusive Sprite Midget Race. The maximum points awarded per race weekend would be 24. The maximum accumulated in the best 2 out of 4 series would be 48 points.
E. A driver will not receive points for a session in which they were involved in an on track incident resulting in a disciplinary action from the VSCDA Drivers Committee.
F. If a driver enters all 4 eligible race weekends he or she can throw out the worst weekends, which will allow any mechanical or other issues to be discounted. Final results will be tallied from the 2 weekends with the most accumulated points unless otherwise notified by racer.
G. An overall winner will be selected regardless of class based on a perfect score of 48 points from 2 race weekends. If more than one racer has highest points accumulated it will be considered an overall winner tie.
H. Awards will be presented at Grattan per the above Class Categories at the end of the last Group 2 race.
I. These awards are in the spirit of Vintage Sports Car Philosophy recognizing fun and durability by completing the most laps per race weekend contributing 1/3 of total available.
V. Race Series Special Awards (these awards will be determined by drivers and crew and awarded with end of season awards):
A. Gary Kropf Spirit Award for Vintage Spridgets (Traveling Large Piston Award). Criteria:
1. Fast, safe, courteous driver, (promotes the “vintage spirit”)
2. Assists others within the paddock – repairs, parts, advice. Willing to jump into help and assist other Spridget make the next session.
3. Quick to organize group activity – brats for lunch “all pork weekend”, watching other group races, from the best vantage points, coordinating seating at dinner, etc.
4. Volunteers with the VSCDA on committees, and sub-committees
B. Jim Donato Sprite Midget Race Series Most Respected Driver Award (Traveling Steering Wheel in a display case Award) Criteria:
1. Predictable / Trusted (uses mirrors, points faster cars by, passes safely and allows others room to pass and is always a defensive driver over winning at all cost), stays on racing line except when car failures would leave fluids on track or safety is a concern)
2. Objective: Listens to others and approaches other drivers that may have an issue with in an open and fair way. Can sit down with any driver and feel comfortable that they did the right thing when on the track.
3. Observant: Looks forward to observe incidents and flag stations, inspects car between sessions for safety to avoid causing accidents to others on track.
4. Respectful: Avoids Red Mist, which is identified as an emotional win at all costs attitude and maintains Vintage Spirit Philosophy.
VI. Abbreviations and clarifications:
GCR = SCCA General Competition Rules
PCS = SCCA Production Car Specifications
ERA Correct = 1972 SCCA GCR for Group 2 Production Sports Car Class (Bug Eye & Square Body). Up until this time we have only had 1275 engines for Square Bodies. Other considerations will be made if 1098 or later 1500cc race cars join us.
M1= Modification Preparation (This class is for Spridgets more slightly modified beyond ERA correct including all Bug Eyes over 1098cc and or additional weight reductions of 10%)
M2= Modification Preparation (This identifies Spridgets more highly modified beyond M1 with more recent SCCA raced cars and or additional weight reduction of 15%)
VII. Misc:
This document is a “Work In Progress” and can be expected to change in the future based on understanding other Vintage Group requirements and our own consensus of what seems reasonable among our group. We are open to any thoughts of how to improve this fun Vintage Spridget Racing series. This series is for fun on and off the track. There is a class for every level of preparation. Please contact Stan Mason = StanBMason at AOL.com. This is open to anyone interested in Vintage Racing a Spridget with us and of course it includes our typical joint cookout for all attendees usually Saturday and Saturday Lunch.
