Hi Mark,
Planning to stay within the threshold regulations
https://www.lvvta.org.nz/documents/s..._Threshold.pdf such that there is no lvvta involvement. Alas that also includes not moving the petrol cap....
The only reference I can find to chassis rails is in
https://www.lvvta.org.nz/documents/s...tal_Impact.pdf section 2.2.2.b
Code:
any chassis rail or sub-frame rail bridging components provided by the
vehicle manufacturer (such as structural tie-bars behind the front
bumper) are not removed or significantly modified.
Which is a recent change, so certifiers will still be building experience around that, but as far as I can see does not apply to the Z3 bumper.
Cheers,
Ido
