Outer Limits 4x4 Board

want to get 33's and longer shackles engineered on the hilux so if i have an acident insureance dont knock me back...

the car has already been engineered once for every mod it has so i could get it registered in the act....but now its got the tires and shackles can i just go get them passed, put the report in the glovebox and be done with it?? or do i need to take the veichle back over the pits??
concern is that if i have to take it for another full inspection at the rta or whatever, things like the exaust db's wont pass..

cheers..

the best way for compliance is get a new eng'rs cert. , then get an adjustment of records (blue slip ?) then off to the rta for new rego papers. A t least this way its all noted and legal, which in this day and age where everything is to do about insurance and litigation, the smartest way to do it
