“Entries remain open for a day and we are expecting a few high-profile additions to the current list before the final grid is settled.
“Fans looking to attend should book their tickets now to make sure they don’t miss what will be a remarkable field tackling the Mountain next February.”
Nissan has elected not to enter this year after a four-year stint in the event with factory-backed GT-Rs, which included winning in 2015.
Work continues to get Hobson Motorsport’s privateer GT-R on the grid, although no entry has currently been lodged.

Fellow Supercars squads Tekno Autosports and Walkinshaw Racing also competed in the event this year but do not currently feature on the 2018 entry.
