I'm running in B Street, so just the front bar. The specs on the front are supposedly the same as the Dinan. From memory - 32mm hollow? It may actually be stiffer or it's partially me. I did have three years in a C6 Grand Sport with a very soft front spring so driving around pushiness is not new. Definitely still have some fiddling to do with the M2.
