I shouldn't think they will do much more than they do now mate, they try to defect anything that looks souped up(makes sense really)
This is why I say keep the car looking stock, let them pull over the lancer with 100kgs of rice tacked onto it
My car looks almost stock, not very much gives it away, it just looks clean and sleek and I get pulled over on a regular basis due to working in a nightclub and driving at strange hours when they are likely to target drink drivers. They always just do an RBT and send me on my way after telling me the car looks nice(HWP too).
