The F30 328i starts in TTD. I ran the Nitto NT-01s on my prior e36 M3 as well, but in TTD. I'd be currious to hear what you guys come up with as the widest set up for the F30. I suppose it depends on whether you have camber plates and/or run spacers. Also, certain coilovers may give you more room inside.
