Hobbs is pretty much the only choice..if you priced the other guys who's eligible to do it, Hobbs by far is the cheapest. Plus if you drive the car or even tow it, AQIS have argued foreign soil could be blown off your car while it's being transported or driven so they could technically give you a fine for that. Safest thing to do keeping these idiots happy is to send it down to Hobbs.
As with the rims, I am fairly sure they will survive. At least my EVC, turbo timer, gauges and a good number of other gadgets survived. The only thing vanished is the head unit but that's pretty much expected. Even the stacker is still up the arse end. There were times I've had exhaust, suspension, bodykit sitting neatly up the back and it made the trip..
Clearing it out of Customs isn't as scary as it sound so long you've got all the paperwork that they wanted. Then again with a customs broker might save you a bit of hassle with those idiots at Link Rd. Lately they've been shafting people for minor thing.
