not to sure on there legalities, but i do know of a few cars with them, great if you have a race seat and cage with intrusion bars, i used to crew for a midget (speedway), that had one, be careful, one night it wasnt clicked in properly and umm yeah, maybe lockable is the way
The rules that i know are, if the car is road legal you can only have an approved type as you cannot have the mechanisum that you chop and weld the detaching hub to the steering shaft. If the car is not road legal then you can do wat u want as long as it is safe.
The entire car will need to be certified once it's been rebuilt so no issue there. Just need to know what is and what isn't legal before I go and order one Just wondering if anyone knew for certain - otherwise it'll be a phone call on Monday Gary
I remember reading something about these and from what i remember there are two types, one of which can be released by hand and one that requires some special keys to be inserted before being able to be released and the jobbie with the keys was legal for road use and the non keyed one illegal for normal road use, there should be something on MSNZ site.
As long as it is or a reputable brand and designed for the purpose then it is fine for a WOF. When you get it cert'd you should make sure he notes it down just to prevent any problems.
