Tom Williams and Phil Hall returned to the Cadet Cup after selected rounds in the FIA World Rally Championship. The English pairing adapted quickly to the Manx asphalt and after the first round on the island they claimed their first category win. The Harper Adams University team had been working away all season to spray the champagne. Led byJames McDiarmid and Max Haines Messenger, the team kept clear of trouble as others faltered to become the fourth different Cadet Cup winner in 2017 in their Ford Fiesta National.
Nicky Grist Stages winner Alex Waterman had a weekend to forget as he and co-driver Harry Thomas suffered a roll on stage 15. The MH Motorsport team burnt the midnight oil to patch up the car and get them out for the final day and to take second on the final round of the season. MH Motorsport stablemate Nabila Tejpar scooped a fine third on the opening round before a bent steering arm and broken wishbone forced Nabila and co-driver out of the event.
