I'm pretty sure the 2009- Z4 35i falls into the same BSP class with the same motor as the 135i.

All the non-M E85/E86 can go to STR, the roadster class, so it's not lack of a back seat. Only the Z4M gets jumped past ST into SP. A couple people I spoke to at SCCA indicated the Z4M was viewed as a bit of an overdog in Street, but they didn't want to exclude a stock off the dealer floor model from Street class, but they also thought it would be over matched in A Street so it went into B with the non-M cars.
