I used to be involved in the 2CV championship, and the 24hr races, although in my time they were at Mondello in Eire
If I can help with any info just shout.
I didnt race I just put the car together and looked after it during the season and the 24hrs.
Best team is 3/4 drivers, team manager, 2 good mechanics, and 4 or 5 others who know there way around the car, plus a couple of people to share the pit board duties, that way everyone can get a break etc and there are still enough to sort the car at pit stops. Oh and dont forget the guys doing the refuelling.
We used to do engine changes in 12mins from memory so 8 is very very good.
