Examples of minor (owner certified) modifications are:
engine changes where the capacity increase is less than 15% above the maximum size engine
available for the vehicle (providing no major structural modifications are necessary and where
noise and/or exhaust emission ADRs apply, all standard equipment such as carburettors, exhaust
systems, exhaust gas recirculating valves, oxygen sensors and catalytic convertors relating to
noise and emission control are retained and operate correctly);
and
fitting a “package” available as optional equipment for the vehicle (eg front disc brakes, power
steering, alternative transmission and bucket or bench seats);
