Nationals 2007 regs are out. Really thought they would give everyone more notice than the rollbar & harness changes.
The main changes from 2006 are:
* Roll bars are compulsory for open top cars. Minimum single hoop behind drivers head.
* Any vehicle that runs faster than 1 min 11.99 seconds will be required to have a Roll Bar behind the drivers head that is constructed of steel tube with a minimum 50 mm OD and a wall thickness of 2mm or 44.45 mm OD with 2.5 mm wall thickness. It must be at least 50mm above the drivers helmet and will be fixed to the chassis in at least three separate positions.
* Any car running faster than 1min13.99 seconds will be required to have a Full Harness Seat Belt.
* Fire Extinguisher must be less than three years old or should carry a current inspection tag.
* Accelerator linkages will have a minimum of TWO return springs.
