[335xs2dinan]

The answer may also depend on what other changes come with the awd m3. With the old e9x I went with the 335x drive not realizing the differences in suspension between that and the rwd models. Those details are beyond the scope of this post but doubt that the m3 awd suspension (compared to rwd m3) would be as drastically different as the 335xi vs 335i. Anyway might be worth looking into any other trade offs (suspension or otherwise) that may come with the awd variant m3.
