National 4s

Dennis Richardson

National 4s are the new 1600s at Nowra Speedway, with very slight rule changes. The decision was made by the drivers of the 1600 sedan category to move forward and adopt the National 4 cylinder rules. Mechanical specifications remain the same but engine size is now opened up to include a maximum of 3000cc. Street tyres instead of racing tyres will be required from the start of this season and the regulations ensure that "super" four cylinder engines are not allowed.
