Personally i dont uonderstand the ADR change re the 5 and 3mm wheels.... People keep saying early cars had the 5mm wheels but i just sold a 5mm wheel dated stamped 8/2/77 part number was for an 8VD (SS or a9x)

What i dont get about the whole 5and 3mm question is..... How does de engineering something make it safer and why would the ADR rules body need to get involved...
