Hmmm.... The M coupe is the most structurally rigid car BMW has made to date. It has all the reinforcements of the roadster, but also have a fixed roof.
The difference is like 300 percent or something. But I doubt you can tell that much. The Roadster sufferers from cowl shake, and has rubber dampers bolted to it to try and fix this problem. The coupe doesnt need anything.
