No, mine are not factory cut outs.That green pic of the front cut out IS factory, from a Sandman ,courtesy of a forum member I took stencils of these and transferred them to mine and did the cut outs,the front and rear spoilers were an option on GTS Monaro except HZGTS,not sure about Sandman?in my experience I have rarely seen the factory cut outs on GTS or Sandman ,maybe front ends get changed over the years.
