i got thru regency with a turbo-back zorst, xenons, WAY too dark tint, front mount, lowered ride height - everything else standard. I took off the fat wheels, boost cont, turbo timer etc and cleaned it up nicely.
The guy who inspected (George was his name) was a champion - he said 'Mate your car looks a little bit lower than standard and your tint is WAY too dark. And im not too sure about those headlights either...get out of here mate'
I would trawl the evo forums for a standard exhaust and computer, there prob isnt much you can do about the headlights unless you wanna buy some cheap foglights and have a crack at changing them yourself - or pay an auto electrician a fortune to do it. im sure the guys on here will have some tricks up their sleeves
Its all about luck (if you leave the illegal mods on it anyway), and the only reason i risked it is because my missus told me to grow some balls and take it down there before the rego runs out
I pissed three times on the way.
