It's hard to make just any car fit with the FIA GT rules.
The GTLM/GTE/GTD/GT3, etc. and the Z4 platform are a good fit. I believe there will be some new GT rules coming out in 2016 so perhaps after that BMW will look to another chassis to race.
The only other way you'll see one of these race is through privateers and a street tuner (for example) class.
