AS for the oz race cars that was a very long time ago and to group A rules so even if they wanted to change them they can't under group A.
Ask John munro about ND4SPD and you will see its a genuine streeter but we are going to change the car around for a few months to show its tru performance as it has run 142mph down the 1/4 on basic dunlop road tyres wait till we set up the chassis and run semi drag rubber + good fuel and race tune.
