So after some research I have obtained this, apparently last one from the factory so my bumper should be sitting pretty shame they didn't fit it in production !
What is it? Another bumper support? What's the purpose ?
The polystyrene bumper supports all 4 off them that were never fitted to our VXR8 or early HSV E1 in Aus, they fitted them to cars that owners complained of sagging front bumper, but we never got them !
