Hi Kai, We're also in the process of researching and getting our modifications legalised and engineered, wondering how you went with getting your rig engineered with 35's and 4" lift. Our Engineer has asked us to find all the standard factory specifications of our SWB GQ, ei, highest wheel option and highest factory height. No idea where to find these stats, but only just started looking...
any advice, tips, tricks?

thanks
