While they certainly look to be better quality than the OEM placcy plug things that come in the wheels from the factory, 'Spikes' like that, or in fact,
anything pointy or the slightest bit 'sharp' (& there's a definition of 'sharp' in our ADR's that involves something like 'any edge with a radius of less than 8mm', or something along those lines...

) are not permitted on road going vehicles anywhere in Oz! :lecturef_smilie:
If you get sprung anywhere on public carriageways, parking lots, or roads with anything like that fitted to your vehicle here in Oz, it can result in any Police, Roads & Traffic Inspector, Ferry Operator, or Registration Authority issuing your vehicle with a '
Do Not Drive until Repair is carried out, Inspected, & Certified as Road-Worthy' Defect Notice that means you cannot drive it
any further at all, not even to the nearest place of repair; that you need to flat-bed it home &/or to a repair place; and that once the repair/replacement is completed, will still require an Inspection to certify that entire vehicle is now fully road-worthy - and the inspection is usually a very meticulous 'fine tooth comb' type inspection for
any & every possible failure to meet the strictest definition of our road-worthy standards, not just the wheel centres!! So fitting them & riding on-road in Oz could well cost you
Thousands of $$ in flat-bed/trucking fees, repair/replacement fees, plus any Inspection Fees - especially since said flat-bed/trucking may entail fees for trucking it over a fairly long distance just to get it inspected by the appropriate Authority in order to get that Defect Notice lifted - and there's no guarantee that your vehicle will pass that inspection the first time around either, so you may need to take it away for further 'repairs' & then take it back for a second inspection.... or do that more than once!! :gaah:
So no matter how much anyone may like them, they're not legal for road use & so not a good investment for any Oz Spyders!! :banghead:
