The event will consist of three races, each comprising heats of increasing length, and increasing points tally.  
This helps keep alive opportunity to improve in field placing throughout the weekend, and reduces any home track
advantage, as visitors become progressively more familiar with the circuit.

Morning and afternoon tea/coffee and snacks throughout the weekend, and lunch on Saturday are covered in the entry fee. 
There will be a Saturday night dinner organised which is at entrant's cost. Cold drinks available at a small cost.

Cars will be scrutineered upon completion of practice, or earlier if entrant it ready. This requires "body off".  
After scrutineering, entrant may refit body and run some test laps to check it before handing in to Parc Ferme.
Cars will remain in Parc Ferme at the track overnight and be returned to entrants Saturday morning for qualifying.
Cars may be worked on at the venue between heats/races. We do not anticipate any drivers attempting to make modifications
outside the spirit of the rules, and just aren't interested in nit-picking.
This weekend is about meeting drivers from around the country and having fun.

Should any car fail scrutineering; Entrant will have opportunity to bring it within the rules overnight or during the qualifying round.
If he is unable to bring it within the rules, the Chief Scrutineer and Race Organiser may impose a points penalty as they deem fit in
fairness to other entrants, to enable that car to still compete.

  • Qualifying is by way of best solo lap time by each driver in a one minute period.
  • Race one drivers will drive in reverse order according to qualifying times.
  • Races two and three running order will be determined by points from prior races.

We will race throughout Saturday and complete as many heats as possible; then conclude on Sunday if we have over-run.
Racing will not extend past midday Sunday; to enable entrants to safely book afternoon flights or drive home.


The DTM Classic  2021 – a Shootout  - Changes/clarifications from 2019 in Italics

There is a very good early article about these cars HERE to give newcomers some background on DTM and the cars.

The intent is an event which requires only basic tools, allows only low cost alterations from the car as supplied in the box, and is easy to set up;
thus creating a level playing field that will encourage people who have never traveled beyond their home or race group to come and have a go.

It is essentially a "glue, true and fine tune" class for the four DTM models
- the Opel Calibra, all versions of the Alfa Romeo 155, the Mercedes Benz 190e and the Nissan Skyline GT-R 32 "Godzilla" 

Permitted changes are -

  • White Kits to be custom painted in a realistic race livery, let's be pretty about this.
  • Cars may have grub screws fitted to the standard chassis holes to set the front axle height and travel.
    The cup-like chassis supports under the axles and the “runners” originally in the front axle posts may be removed, which I suggest for
    free rotation – they serve no purpose when using grub screws to set the axle height.
  • Front and rear tyres can be glued and trued.
  • Front tyres can be zero grip or original - you can coat front tyres with nail varnish or superglue to make them equivalent to a zero grip
    if you prefer. They should remain the same diameter across the full width.
  • Rear tyres are to be PT1171N22 by This year we will allow tyre treatment, but you just may end up with too much grip – as some
    cars were pretty close to tippy without treatment in previous years. I see it more useful just as a tyre polishing step, to gain that extra fraction
    of roundness and smooth quiet running.
  • Pod and body screws can be run loose or tight - whatever floats your boat and may be of any brand or type.
  • Motors can be glued, screwed or taped in place.
  • Tape can be applied to the underside of chassis/pod to cushion the pod float  (ribbed fibre-glass tape rules)
  • Any spacers you wish, may be used on axles, pod and body posts where you wish - or not
  • Softer braid can be fitted if you prefer – I do strongly recommend this!
  • Weight can be added. All models shall be run at minimum weight 80 grams, maximum weight 90 grams. (The magnet can stay in place).
  • Chassis may be flattened if needed on a steel plate using the typical water bath or heat methods.

None of this is rocket science, secret squirrel; or beyond the capabilities of most folk. Local club members will be happy to help visiting drivers
with fine tuning for the track etc.  

The baseline is -: If it is not listed as permitted, assume you can't do it – or feel free to ask !  And the overall rider folks, we are intending to have fun,
and run a competitive but friendly event as in previous years.

-  I would be very happy to see our local club guys adopting a first time traveler or two in an organised "buddy up" scheme for the weekend, to give
them some help at the event if they haven't been able to set their car up to typical spec.  That would encourage those same new folk to come out
and race for the first time.
