I have found the S55 to be incredibly thermically stable, and that in a stock heavy street car. And no oil consumption whatsoever, which is unheard of in any previous generation M car. Drop hundreds of pounds with a bespoke race car like they did with the M6, bump the HP by 50 or so and they would be in a much better spot.
Bad thing is that it's too late right now.

If it is not hard to make the S55 reliable in race trim, then why did BMW themselves pick and develop the M6 with the TTV8? Why not pick the M4? Again, are claiming that the S55 will last the endurance races, be reliable against the 911RSR, Corvette, Ford GT, Ferrari 488? Or in GTD class, the Audi R8, Lambo Huracan, AMG GT, Lexus RC-F? Many of these cars are making well over 500 comfortably, whereas the M3/M4 isn't. Plus, there is that crank hub issue.
And again, this is not a few laps, these are endurance races. 24 Hours of Daytona, 12 Hours of Sebring, there is the 24 Hours of Nurburgring, and the 24 Hours of Le Mans. If the S55 is as thermically stable as you say, why no M4? Why no S55? It is a lighter car than the M6. The smaller M3 coupe (now M4) has historically done battle with the 911, which is why BMW decided to go to a V8 with the E46 M3 GTR---their inline 6 wouldn't cut it.
