Firstly an officer is going to have no clue about what the car is or what tags it has, he will defect you on what he sees. Nothing will stop you getting a defect.
Been there done that.
It will be then up to you to clear the car with inspections.
I have never heard of some magic tag that enables you to drive the car in the modified state it is in.
P.S I was the one who had a chat to you about the car at the servo on Wed night after the drags White R33.
Also, the car is supposed to be measured with no one in it on flat ground, further proving the officer was an arse or didnt know the rule.
