welcome, another vic (or shitorian as i am know to some work mates) here.
I have never delt witht he pits personally but its similar to getting a road worthy done. Fix the things they put down and clean anything else up. if you get done for the height and exhaust but think they may pick on something else fix it too, unlike vic if you fail the inspection you have to pay again so best to get everything you can think of done.
Hope that is understandable.
Also for drift most people are on driftwa if you have not already found that site.
