In 2015, OAK Racing combined their operations as a racing team in its own name and those of supporting other teams.

They entered the #35 Ligier JS P2 Nissan-Dunlop in the FIA WEC Championship with a trio of gentlemen drivers: Erik Maris, Jean-Marc Merlin and Jacques Nicolet. 5th at the 6 Hours of Silverstone and 10th at the 6 Hours of Spa in the category, the trio crossed the line in 11th at the 24 Hours of Le Mans,

The team also entered a second chassis at the 24 Hours of Le Mans, a Ligier JS P2 Honda-Dunlop, given to a quick and talented crew for whom it would be their first race in LMP2: Chris Cumming, Kevin Estre and Laurens Vanthoor. Unfortunately, while they were in the top 3, their #34 JS P2 was forced to retire one hour before the end.

Alongside this, the team supplied G-Drive Racing for the second consecutive year with a turnkey service in the World Championship. The #26 Ligier JS P2 Nissan-Dunlop took seven second places and three victories and won the title.
