Swap V12 into BMW E34 is not popular modification, but sometimes we can meet such tuning projects. Engine BMW M70B50 is actually 2 engines M20B25. So E34 from beginning has long enough engine bay for such engine. But this one BMW 550i V12 E34 has swapped M73 engine.

When you are looking at this E34, it looks just like ordinary old school sedan with wide wheels. But it's predictable because this BMW 550i E34 has a powerful V12 engine and this car is almost without any electronic assistants, which could help to transfer more power from wheels to the road. Driver is alone against all power from mighty V12 M73. So, these wide wheels are needed. And this car needs really good tires.
