I assume by "optimistic" you meant 0.1 second difference between M8 and M8 GC
Based on base model spec of M8 on BMWUSA website:
Power to weight ratio of M8 Coupe CP is 0.1437 hp/lb
Power to weight ratio of M8 Coupe is 0.1397 hp/lb
Power to weight ratio of M8 GC CP is 0.1377 hp/lb
Power to weight ratio of M8 GC is 0.1339 hp/lb
So with about 0.006 hp/lb difference between Coupe and Gran Coupe I dont expect more than 0.1 second difference on 0-60.
For higher speeds like 0-160 then aerodynamic and friction factors will take the place and Coupe must be slightly quicker than GC due to weight and shape
