Group 1 francorchamps
Sorry if this thread is in the wrong place and please feel free to move if so but.....Could anyone point me in the general direction of the regs that were the Spa type 1973-75 or so "Grp1 Francorchamps"or even the 70's BSCC grp 1,5 please? I have looked around but it all seems a bit 'well they weren't Grp 1 but not as modified as Grp 2'! Were there definitive sets of regs for these oddballs? As far as I can can make out, Goodwood grp1 seems a bit like the francorchamps rules, the ones I'm particularly interested in. I know that wider arches and wheels, free-er carburation and more engine work was allowed than in grp1 but I'm wondering what else. Anyone?

The Group 1.5 regs don't permit wider arches. For the BSCC regs Tou need the App J and relevant Blue book for your particular year. Wheels were homologated diameter and width. Brakes are standard. This is related to a Fiat?

Yes, there must have been written regs for individual countries domestic interpretation of Gp1. But no, I haven't found any yet. I guess within the hallowed portals of the RAC Club, in their huge library, the BSCC regs could be found. Comes down to time and access. Unless you are a member, of course... The Goodwood interpretation is probably closer to CTCRC (apologies if wrong club) Gp1 regs. The wider wheel arches seen in Belgium were specific to the Francorchamps 24hr race, possibly? |

The Goodwood regs are as close to Gp 1 BSCC as anything. They are less modified than CTCRC where you can modify brakes etc. My car is a case in point. We can run a bigger carb but not additional intakes. Suspension is non adjustable for droop and rebound but you can run different springs. Bodywork is as homologated. Not Gp1 which was essentially production saloon.

I should add that my car is running the same componentry as it ran in period. We have photographic evidence. The annoyance is that the FIA doesn't recognize it.

Hi Peter, yes it's about my 128. I built it a few yrs ago now to the 'francorchamps regs as I knew them, then when I couldn't find anyone that seemed interested in that rule set I just left it be. Then I read the goodwood regs, realised that they are not dis similar and started hunting around again. The car is too far from grp 1 and I don't have the budget for a full blown FIA grp2 build and also it would be nice to have something different from that period of racing.

Peter, the Capri next to me had rear discs, and I was told it was not the only one. Or were they allowed to have them in BSCC? (Not that it bothers me- the event is unique and needs to approached as such!)

Mike I'm not suggesting that the there aren't relaxations to fill the grid. However the base regs are Gp1 as per the period for the BSCC.

going back to a chat with the late Gerry M I recall he told me that initially the mk 2 Capri ran transit header tank on its radiator and Granada front brakes. There were other mods too.
Les Holman Blackburn is a Spa specialist. He'd be able to shed some light on the regs of the period. |

The wider arches on Group 1 cars that were on some of the European cars I think refers to Trophee de l'Avenir spec cars. Essentially Group 1 with some arches, wider track and tyres and other freedoms.

That's a big help AntA35 thanks. I hadn't seen that page and learnt a good deal there. Peter, I have discovered that Les Holman Blackburn shared the grid with a 128 of my type in silverstone in '75. Any ideas how I could contact him?

Unfortunately this thread has become irrelevant for a while as I managed to do not a small amount of damage to the car on a hillclimb! Back to the drawing board.....
