As the results of the opening round in Wellington, they are joining the series at a time when the series has been at its most competitive with Grant heading a star-studded group of regulars including Auckland international Daniel Bray and one of the country's most successful sprint class drivers Matthew Hamilton.
This weekend's round is a first for the Mi Sedaap Pro Kart Series on the Rotorua track and series spokesman Steve Brown - who won the Masters class at the opening round in Wellington a month ago - says it could have been purpose-built for the 6-speed gearbox-equipped 125cc karts which run in the KZ2 and KZ2 Masters classes.
"The longer and wider track is certainly going to give us some room to move," he said.
"Even with the field we've now got in KZ2."
Last year Hawke's Bay driver Tom Curran was the dominant figure in the KZ2 Masters class, but with series organiser Brown and fellow Aucklanders Mark Lane and Snow Mooney beating him at Wellington, Curran has serious competition.
There will be action both days with qualifying and the first two heats per class today and the final heat and semifinals and finals tomorrow.
