The 2018 LMP3 Cup Championship was the second season for the British LMP3 Cup. The calendar was announced on 10 November 2017,[1] with the same venues as the previous year, but in a different order. The series finale was held at Silverstone, one month later than in 2017.
Michelin supplied the tyres, a change from Pirelli in 2017,[2] and French manufacturer Norma campaigned an M30 chassis, the first non-Ligier JS P3 in the series.[3]
