Both of mustangs are modified and yes i could get booked if the QLD transport dept pulled me over and got nasty . Take my wheels std was 14x5.5 now 15x 8 and thats a no no ,can only go over 1 inch total not each wheel ,then the rolling dia is increased no no again .Must have a min 100mm ground clearance does yours ,here they have a rod with wheels on it that they run under the car it hits your done . Now this is a tricky one and they dont act on thank god, but you are not aloud to increase the power of your engine more than 15 percent from its factory specs ,etc,etc .Might buy a hot rod and once it passed thats it ,they, the police etc can not defect it as it has been passed and was built that way .
