Run by the British Automobile Racing Club’s North West Centre, the CNC Heads Sports/Saloon Car Championship is a cost-effective category that is open to all manner of cars regardless of their make, model and power.
Started in 1984 as a special GT championship with a small core of regular enthusiasts entering races, the series has grown into a successful and stable championship which boasts grid of more than 30 cars on an almost regular basis at each event every year.
To be eligible to compete in the CNC Heads Sports/Saloon Car Championship cars must have been originally designed for road use and are then split into two basic categories, Special and Modified.
These two categories are further divided into three classes based on engine size, the splits being at 1600cc and 2500cc in both cases. Points are awarded within each class and the overall champion each year is the driver with the most points.
