Good to have a nice old fashioned barny with you, Fax, about something important.
I cannot say that I blame IMSA for ignoring the ACO rule on this one, though. Another year of single marque domination for the overall win could have had serious consequences. At the end of '06 it would have been hard to believe the title of this thread!
However, if the RS Spyder or the the Acura make it to Europe, they will have to play by the rules. The choice will have to be made : either they comply with the ACO's LMP2 regs which are designed to help ensure that they don't get the overall win unless the LMP1s fail to finish, or suffer major reliability problems; or they compete as LMP1s - which is perfectly possible.
Genuinely private teams - if such they are - understand and appreciate this philosophy, which is how Juan Barazzi, Ray Mallock, Bruichladdich et al have competed in Europe. Victory for them is victory in LMP2. What happens to them if Acura blaze in, in whatever guise, and hijack the class? Whether in the Lowes Fernandez or Highcroft livery, the factory and a pot of money will not be far behind them.
I appreciate your point of view and accept that for ALMS to stay healthy (? 36 entries at the greatest race as opposed to over 70 competing for just 55 places at LM) IMSA could not do much else. However, we are looking forward to great battles in all four classes for the first time for years. I can't help but think that the ACO must have got something right.
The situation is very similar to the Porsche effort in GTP in the 80's & 90's. Porsche ran the cars then sold them to private teams, there would be 8 to 10 entries in GTP class. Then BMW, Jaguar, and eventually Nissan and Toyota jumped in to the mix. It made for a lot of entries and a lot of competetion, which would be nice to see again.
