this is mainly for ego and few others who have their ride heights engineered ...

what was the criteria u had to pass to have it engineered as a safe roads worthy mod and how much did it cost u thanks

I'm also interested in finiding out more about this process...

Looking into what I need to engineer the wider wheels etc for my Ralliart.

/Edit: Attached is the requirements for WA

Its much like engineering anything else - go to the RTA website for your state, look up engineering signatories, and find someone who is close to you who either does everything, or lists that they engineer suspensions etc.

Certificate is usually around $150. You have to provide it to the RTA and your vehicle is recorded as modified production (IIRC) - you also have to keep it in the glovebox for cops.

Yeah find an engineer and have a chat to them.. Thats what i did with mine.. ride height is a big factor and also suspension travel..:)
