The 2021 Carter’s Tyre Service South Island Endurance Series has had an influx of entries for both the One and Three-Hour events. With more entries than grid spots for the One-hour events, organisers are to host two One-Hour races at each of the four rounds that make up the championship.
Since entries opened, over 60 teams have signed on for the One and 23 for the Three-Hour.
The SIEDRC plan is to split the One-Hour races by Class, so have Class A & Class B together (basically a 0-3500cc race) and then have Class C & Class D together (basically a 3501+cc race).
The committee will retain the discretion to amalgamate the two races back into one if they receive less than 40 entries for a round.
