Track would not create more grip, you would not prep outside same as during summer, difference could be just more of same prep, could be need little more aggressive prep, in either case good chance prep would need applied with heat, good chance hot box would help a lot, possibly might end up with little more internal prep than during the summer as well.
As an example we have a track here during summer would be 80 cc internal maxxis wiped during the week with some medium base prep, then at the track race day wipe hard track VS late fall a lot colder would be 120 cc internal wiped twice as much medium base prep during the week, then wipe medium base prep at the track and use a hot box.
