Rear wings - legal or not

[KlRGT]

Hey guys, I have a 2020 Kia Stinger GT fitted with a Stingerhaus Body kit and Rear race type wing, I’m in the body repair trade and was pulled over by cops and was given a defect notice for the rear wing and front wings on bar and front guards. 
 

asked the cop why it was illegal and he could not specify why exactly except saying it could injure a pedestrian ? 

anyone know the laws around these?

Is the wing wider then the rear of the car? 

[KlRGT]

No it’s not, easy 2 inches in from rear wheel arch on either side.

Generally....

Side skirts and front and rear spoilers may be fitted without specific approval, provided road clearance and air flow for brake cooling are not adversely affected.

Additionally, they must not be fitted so they are likely to increase the risk of bodily injury to a vulnerable road user coming into contact with the vehicle. All material is to be of a suitable thickness and be free from sharp edges or corners.

Rear spoilers must be within the body shape/outline of the mounting surface, for example, the boot outline. The minimum thickness of end plates is 4mm and they must be free of sharp edges or corners.

Having said that, I'm only familiar with NSW and QLD legislation/regulations, VIC might be different.

Cheers mate. 👌

The rear wing endplates and stands don't meet the requirements as above - They need to me smooth and not sharp.

There's some examples of legal wings. You'll note that every OEM wing follows this kind of design principle.

This is a subject that pi55es me off; tank-life 4wds can be fitted with steel and aluminium literal battering rams on the front, winches, spotlights, steel bike racks on cars etc and apparently it's fine. Yet you get told those front wings are 'illegal' and hazardous when they appear to be constructed of a suitable material, no sharp edges or corners, don't protrude more than 150mm from the body outline, etc. The section of the Code which covers this is so vague and brief, and open to interpretation for the most part that it comes down to the individual's point of view.

Eg " All material is to be of a suitable thickness " suitable for what? Thick enough not to constitute a sharp knife-like edge, or not too thick that it still creates a breakable/collapsible structure in the event of collision? Depends on the specific part of course so, open to interpretation.

Looks like your wing endplates all have rounded corners rather than sharp points; are the end plates more than 4mm thick?

Not to mention ladder racks and trailer steel mudguards.  I have a rear wing, haven't been accosted by the law yet but its always there!!!  I think the reasons and the 'law' is an ass on this...they should be focusing on real lawbreakers rather than displaying their awesome power by nitpicking.
