Superstocks
Racing car class in New Zealand
From Wikipedia, the free encyclopedia
Superstocks (previously known as A Grade Stockcars) are a class of New Zealand Speedway (dirt track racing). Cars are designed with integral roll cages built to rules provided by Speedway New Zealand. Superstocks weigh 1,400 to 1,500 kilograms (220 to 240 st; 3,100 to 3,300 lb) and are usually powered with modified production car engines of up to 248 cubic inches (4,060 cc). Contact between cars is allowed and is intended as part of the class, with the closest finish in the classes history coming at the Sharp As NZ Superstock GP at Oceanview Speedway during the 2023/24 season with who at the time was the current 2NZ being Josh Prentice beating Wanganui Local 26V Kailen Mooney by 00.014 Seconds.
