Hi All

This a follow on from the Beta Coupe enquiry, but I guess covers the Stratos as both homologated at the same time from what I have read.

So, if anyone can enlighten me on this I would appreciate it.

My understanding so far…..

Group 3 was a classification for standard road cars with very restrictive (no?) mods allowed to standard production other than safety etc. Min production was I guess 500 given the amount of Stratos's produced.

Group 4 was for modified cars which qualified for Group 3 with only mods being the parts listed in the additional homologation papers to the original Groups 3 ones. No limit on production quantities etc I assume?

I know that is a quick summation of the rules in 1974/75, my main query is WHAT mods were allowed to Group 3 cars as obviously you could not enter a rally with a fresh off the production line car? Also with the Beta engine, there is a well documented issue with oil pump starvation which will screw the bearings under hard cornering, would sump mods be allowed etc in Group 3?

Sorry if this has been covered many times before, but a quick search did not find much on the subject.
