My wheels will likely be either 17x9 or 18x9, squared set up. I'm not sure on off set.
Has the F30 been classed in TTD already? I run the NT01s in TTC on my E36 M3. I love that tire.
I also have an F30 that I will be putting APEX EC-7s on. You can run a 245 if points allow it and TC Kline says a 255 square on the F30 is very doable.
I work at APEX and we will be doing some fitment testing on the F30 to see what the maximum width fitment is, with and without modifications.
