  • Club By Laws

G.V.A.C. Production Sedans is all about affordable racing and the enjoyment and excitement of being able to race a car.

G.V.A.C. Production Sedans endeavour to display a form of racing that tests driver?s skill and vehicle performance. With these rules

G.V.A.C. Production Sedans can conduct feature races that create excitement which enhances the profile of speedway racing in general. 

If G.V.A.C. Production Sedans are invited to race at another track apart from Rushworth, as G.V.A.C. Production Sedans, it would be preferred that all participating receive tow money rather than prize money for the top three place getters. 

G.V.A.C. Production Sedans has progressed to a point where rules and regulations have been compiled to inform and advise current and future competitors, of the standard required to race. These rules have been set for the safety of the competitors and the sport. Like all club based activities these rules need to be governed and enforced. If rules are enforced by the Chief Steward or Club Official it is deemed lawful until the contrary is proved. 

To be eligible to race in G.V.A.C. Production Sedans, a driver must be a financial member of G.V.A.C. Rushworth. Nominate his/her race car at the start of the season as G.V.A.C. Production Sedans.  A new member or car can be accepted at any stage upon payment of all fees required and having his/her car day lighted by Official Scrutineer/s. 

Once registered with GVAC Production Sedans you may move up but you will need to get your car re daylighted as GV Open Sedan. Once up you will not be able to come back to GVAC Production Sedans for the remainder of that race season.

As directed by G.V.A.C. these rules will remain unchanged with the exception of safety rules imposed by the approved insurers or the committee until the end of the 2018/2019 season when the 2018/2019 committee will review the current rules.

Authority to Exclude & Scrutineering: 

All vehicles must present their log book and vehicle to the G.V.A.C. Scrutineers every race day prior to the commencement of racing... No log book, you must buy a new log book $10.00 prior to racing. Scrutineering will close 1 hour prior to start of race meeting. 

If a G.V.A.C. official determines prior to the race that the race car does not meet the applicable specifications, the car will not be allowed to compete unless, in the discretion of the official, the deficiency:- 

a) Will not adversely affect the orderly conduct of the race. 

b) Cannot be corrected in time prior to the qualifying heat/race for that event. 

c) Will not provide the competitor with significant competitive advantage over other competitors. 

d) Is so insubstantial as not to warrant a determination that the car is ineligible to race. 

If the official permits the car to compete under these circumstances, the official will advise the competitor in writing of the deficiency, in the log book and if the deficiency has not been corrected by the next race meeting, the car will be prohibited from competing in any future event until rectified. 

Day lighting of vehicles must be done prior to race day at daylighting days or at the scrutineer?s discretion at a race meeting. 

Feature Races or Season Final: 

To be eligible to compete in any ?Feature Race? or title event a car and/or driver must have run at least three events as a G.V.A.C. Production Sedans in the current season

State title event format: 

To be determined by class representative 


Specs listed in this book are the rules. If ?ÍT? is not in the book, enquire for prior clarification or approval. 

Race Numbers

Numbers that can be used are 4-99 101-199. New cars entrants are to contact the Secretary for availability of number. Numbers 1-2-3 are reserved for the top point scores or title holders in the previous season.

Race numbers will only be held for 12 months with a deposit of $50, and you MUST also be a financial member. After 12 months your car must then be at daylighting days and registered prior to season to keep your number. Otherwise your number will no longer be available.

The top 3 place getters original numbers will be an exception. 

No 00 numbers permitted

Build Specs for New Cars:   

When designing/constructing G.V.A.C. Production Sedans. 

If the design or construction is dubious or questionable to this rule book, it would be advised that you contact the Production driver representative for advice before proceeding.

If the representative is unsure he/she will consult with at least 2 scrutineers and refer to the rule book before providing an answer with a valid reason, pointing out the relevant rule.

The decision that is handed down is FINAL.
