The Nissan Car Club is having a two day event at Sandown Raceway on the 25th & 26th of July, and is open to all CAMS affiliated clubs, Saturday is an un-timed "practice " day, and Sunday the timed "Sprint" day. $150 per day or $270 for both. Usually this is a well organised annual event. If you just want to"do" Sandown, Saturday is a fun day with less pressure, and you can do a passenger run. Be aware the scrutineers take their job seriously!
