NASCAR Supplier

Smiths High Performance also offers material supply support to the US motorsport market, primarily in NASCAR and IndyCar. NASCAR, in particular, is a more stripped-down form of motorsport and yet presents unique challenges not present in other autosport franchises. The cars are heavy and less predictable and speed around an oval track at speeds of 200 mph. While it may not be a sport for the 'purist', NASCAR has a substantial Global following and often offers a more thrilling racing spectacle.

IndyCar offers a combination of oval and road racing where the cars have certain similarities with their Formula 1 counterparts. The prestige of the sport has glamour events too such as the Indianapolis 500. In both series, we supply high-performance alloys and plastics for a variety of car critical applications.
