As there is not a lot of interest on this forum and it is a bit difficult update in so many places as well as difficulty removing attachments so it is getting a bit messy please refer to any of the following links for further details.

I will update here with new posts regarding race results once the series is underway.

Sorry to all if this is inconvenient, I will still monitor it.

Preamble
The intention of this proxy is to encourage imagination for designers, builders, modelers & tuners, it is not to say that RTR and kit builds are discouraged, they are more than welcome.

The Grp5 class was so unique and open that it had to appeal to every kid’s imagination of the possibilities of development, as such please imagine & create to your own ability and imagination.

Racing to commence 5th-6th July 2025. (All things being equal)
Cars to arrive no later than 1 week before to allow testing, warm-ups & repairs as required.
Any late arrivals will be included and raced in the state received.

Entry fee
$30 USD entry fee covers worldwide postage.
Entry fee is per person no matter how many cars entered.
Hosts are excluded entry fee for their own event.

Entries
Max three entries per person in whatever scale they like.

Classes
Individually raced in each 1:32 & 1:43

Classes are to be confirmed subject to number of entries and may be amalgamated if determined by the host.
1:43 & 1:32 will still be separated out though.
Possible classes include;

RTR
3D Print
Scratch Built
Overall Beast of the Beast, if you will.

HOMOLOGATION

The Car
Any car that meets the following criteria.

They must have been able to meet the criteria of the FIA Group 1-4 classification from 1975 - 1982.
NB. It is up to the entrant to provide evidence.
Between 1972 and 1989 there must have been a minimum of 1000 1:1 touring cars or 400 1:1 grand touring cars produced each year.
- I realise that the Group 5 ended in ’82 but some cars were continued in production, and it is too hard to break down the construction numbers for individual years. I’ll be working on total production numbers / years of construction to give average, if they meet the above criteria then “sweet as bro’.” Otherwise convince me.
- As not all cars that ran were brand new allowance has been made for cars up to three years old at start of this class of racing.
  - For example: If the entire run of the car was manufactured between say 1967 & 1974 and met all other requirements then it is eligible.
They need not to have ever competed in a 4th Gen Group 5 competition, just need to meet the base criteria.

Body

Width
The FIA requirements state a maximum body width of 2000mm (62.5mm 1:32 or 46.5mm 1:43), excluding mirrors, side exhaust, door handles, but because the likes of sideways/racer take a liberty on scale,

the body width is limited to 65mm for 1/32, 50mm for 1/43.
To compensate for the oversized bodies the wheel track is restricted to the 1:1 requirement of 2000mm. Meaning that the track to the outer side of the wheels, front or rear, is restricted to 63mm 1:32 and 47mm 1:43.
Regardless of the above points - All sideways cars are valid but wheel track must be as close as practical to the above dimensions, this may mean narrower tyres.

Length

Seen from above, aerodynamic devices need not follow the contour of the shape of the car.
Those which are not homologated for series-production must fit within the car's frontal projection.
ln the front
- They may not exceed by more than 10% the wheelbase of the car (measurement made from the overall limit of the coachwork)
- and they may ln no case exceed by 20 cm the overall limits of the original bodywork (Art 269 b)
- they will compulsorily be installed below the horizontal plane passing through the wheel hub and may be inscribed between the lowest suspended part and the ground.
ln the rear
- They may not exceed by more than 20% the wheelbase of the car (measurement made from the overall limit of the coachwork) and they may in no case exceed by 40 cm the overall limits of the original bodywork (Art 269 b).

Notes

The overall length is guide only, I won't be too strict on enforcing this.
No car will be disqualified, but a penalty will be imposed for indiscretions. This will be a pro-rata calculation based on average times of the rest of the field for each race.

Basic Requirements

The base body of the car must represent an actual car from that era.
The final shape of the car body is open so long as the modifications are additional to the base body and meet the dimension criteria.
No removal of the base body shape is allowed with the exception of original wheel arches and underbody areas to make way for guide or chassis supports.
Mirrors are optional.
No Vac formed
Tyres must be fully under the fenders. No tire may project beyond body work, as viewed from above
No guide must be visible from above
Driver must be visible and at least represented by a head, partial arms and steering wheel in part, make an effort, at least paint a helmet and overalls.
Windows must be translucent, substandard translucent ok so long as a driver is recognisable.
Headlights & tail lights must be represented but do not need to be illuminated.
Body must be min 1.0mm clear from track.

Tyres & Wheels

Tyres to be rubber of urethane only, NO silicon or foam.
The rear wheels cannot have a smaller diameter than the front wheels.
Low friction coating of front wheels is permitted such as CA glue or nail polish.
No treatment of rear tyres is permitted, any oozy/oily material will incur disqualification of the car “NO EXCEPTIONS”.
Rims must be from era and appropriate for car entered, scaled appropriately from 15” to 17” (1:32 12mm-13.5mm or 1:43 9mm-10mm).
Max width of tyres both front and rear is 10mm for 1:32 & 7.5mm for 1:43
Minimum width is 5mm for both scales

Chassis
Open, whatever you want to do subject to the following;

Min 1.5mm clearance from track to underside of chassis at lowest point
Bottom of motor to be min 1.5mm clear of track
Inline, angle or sidewinder is acceptable.
Guide must be able to make Scalextric R1 turns.
No guides greater than 6mm depth with braid.
No magnets

Motor

Home track(s) dudes - Recommend no greater than 21k but open.
Max current draw of 2 amps.
No capacitors or other electrical devices may be fitted to motor circuit
Open can is OK.

Livery
Livery is open to imagination but must adhere to the following;

Must have same number on
- both passenger & driver doors
- or may have number on bonnet in lieu of door numbers
- or all three locations
Numbers must be individual no double ups (please advise number wanted ASAP so you do not miss out)
One small letter after number is fine to differentiate between cars.
Livery must be in keeping with the era ..... no google or facebook sponsors.
Sponsor need not have existed but must be era appropriate
example.
ZeGas Racing Supplies ---------------- fine
ZeGas Computer Repairs -------------- not
No metallic paint body colours ..... excludes wheel rims.

Prizes
Prizes will be trophies only supplied by organiser for the following;

Overall placings 1st, 2nd, 3rd in each 1:32 & 1:43 class
Concours D'Elegance 1:32 & 1:43
Concours D'Imagination 1:32 & 1:43
Lantern Rouge 1:32 & 1:43

Additional prizes will be by donation (to be confirmed)

I was initially seriously considering entering this one but have too many cars to get ready for other proxies but will follow with eagle eyed interest...hopefully videos will be available too Thumbup

Initial post driver list updated

RE: 2025 - Mad Man Motoring (Triple M) Proxy - Group 5 - 1:32 & 1:43 - ZeGas - 16th-Dec-24

I've been a bit slack with the updates of late, run up to Christmas has been very busy, my apologies for the tardiness.

I'll try and find time after Christmas to provide all the track details and photos.

Brumos RSR - Brumos RSR - 16th-Dec-24

Looking forward to this and would like to change my number to 33T and reserve 3 in the event of a second car if that’s ok.

Still the M1?

I’m not sure, but will keep you posted. Have you started a builds page on one of the forums?

RE: 2025 - Mad Man Motoring (Triple M) Proxy - Group 5 - 1:32 & 1:43 - ZeGas - 16th-Dec-24

Not yet,
Next years job

Minor rule addition.
For those creating/modifying their own bodies the below has been added to the rules

"Maximum length is 4750mm (1:1) which 152mm (1:32) & 111mm (1:43)"

I cannot find the reference in the FIA rules that is referred to for confirmation but will keep searching.

This length has been set based on what I believe is the longest off-the-shelf Group 5 car, the Sideways/Racer Ford Capri.
I cannot remember if Moby Dick is longer, I'll measure tonight. If it is I will alter this rule.

RE: 2025 - Mad Man Motoring (Triple M) Proxy - Group 5 - 1:32 & 1:43 - ZeGas - 18th-Dec-24

Maximum length of body including front and rear aerodynamics set to 5100mm @ 1:1 which is 160mm (1:32) & 118mm (1:43)

Rules updated
