Thanks for the replies everybody.

Mike. That is an option I'm looking at. Swapping the wheels and changing the pins to wheelstuds for certification.

Jim. If I can get them to accept the pin drives, I don't think the KOs will present a problem except we may have to do something in brass and lockwired.

Ron and Howard. Once the car is on the road after it's initial certification it won't be a problem. I agree with you about dealing with govt employees. In this case I am fortunate in so far as the local Constructors Car Club is allowed to certify members cars. They are very enthusiastic, proactive and positive and will bend over backwards in their interpretation of the rules to try and help the cars comply.

They won't compromise on safety though and they can't approve anything that is not allowed under the legislation. This is not a safety issue, it's a legislative issue, there appears to be no provision in the legislation for pin drives. Wire wheel type KO's with splined hubs are fine. I'm trying to get them to interpret the pins as a spline. Not sure how that will go.

Initial certification of cars by the club is very thorough with inspections during construction, and when completed, road tested on the track to check handling and braking prior to being certified. Really a very builder friendly process from these guys and they are immensely knowledgable and helpful.

Many of the other certifiers that non-club members must use are inconsistent, obstructive, and won't approve anything that's not built out of 1/4" plate!!!


There is another NZ member on this forum whom I have just contacted, he is planning on using pin drives also. He thinks the constuctor of his car has it sorted. If that's the case that will make it easy for me. He is getting back to me in a couple of weeks. Otherwise it will be up to me to do all the groundwork and hopefully set the precedent.
