Nissan intended to enter two GT-R LM's in the 2015 FIA World Endurance Championship (WEC) starting in April 2015, while a third car would be entered for the 24 Hours of Le Mans. By the time of its planned debut at Silverstone, drivers had covered with the GT-R LM in testing but its first racing appearance was delayed until Le Mans because the car twice failed its crash test and was forced to miss the WEC pre-season test session at the Circuit Paul Ricard. The first crash test ended in failure because the car's front roll hoop was damaged. Engineers were also mandated to redesign the car's door because the FIA decided they should have include an anti-burst load but failed its test first time around and the door's structure was entirely altered following its skin cracking. Testing resumed in April with four days' worth of endurance running with amassed at the NCM Motorsports Park race track in Bowling Green, Kentucky.
