roof chop etc

[xmfalcon]

Hi guys, I'm building an XM falcon, and I've decided to ask questions after I've pretty much done the work! so I hope its right. I've completed a 3inch roof chop (yes its a 4 door, dont recommend it to anyone! but will look good) and also cut the rear end out and replaced the back half with a new chassis clip as it will be tubbed with triangulated 4 link. For both the above modifications, was there anything that was critical for cert? I remember asking a local certifier a while ago before the build and he said if I was confident and competent I could do it all as long as it looked tidy and safe. The other thing going into the vehicle will be airbags, once again I also remember someone saying they can be certified, if they cannot be adjustable over a certain speed. My idea was to link them to (if auto) an inhibitor switch but the certifier did not like the idea of that.
Any help appreciated,
cheers

Hi Bradley, sounds like a neat project!

I think what you're asking is a little complicated for a reply on a forum, as there are such a large range of factors that come in to each of the modifications you've mentioned.

The advice I'd give you in this case is to:

(1) Get your hands on a copy of the New Zealand Hobby Car Technical Manual - this is the car modifiers 'Bible', it's full of helpful hints, tips, and also the rules and requirements for building or modifying a vehicle.

(2) Get in touch with an LVV Certifier with the 1D category at the earliest possible stage, and have them inspect the vehicle at different stages of the build. The Certifier will be able to give you advice and guidance through your build, and having the progress inspections will also make the final certification process a whole lot easier.

Here is the Certifier list. You'll need a 1D category certifier to certify the extensive body mods, chassis replacement, and also the air bag suspension. www.lvvta.org.nz/LVV%20Certifier%20List.pdf
