The schedule & supps have not been published yet because the Sebring long course Feb. 7 (test day), 8 & 9 "Cabin Fever Cure" registration is not up yet at motorsportreg.com.
The word is there will be a specific run group for F600/FV/FF as their "Major" - no split start with the winged and P cars but their own race.
Further, the word is there is quite the interest being made to gather a lot of entries so far.
