MMMMM, this is going to be an interesting thread, i own all 3 motor layout and personally my mid motor car is the most consistant out of the 3, but the mid inboard (tm2) gives a much better feel and can be driven harder, resulting in faster laps, not necesarraly cleaner laps because of the corner speed, but my driving is addapting to the car and the consistency is getting there.
As for 3 classes of 2wd, yeh bring it on, because us older guys that used to race rear motor will probably all race that class because of the nostalgia aspect, lol
