Tell them to get f**ked mate. Theyre just a tad jealous they your doing something different. Im getting the same off people. I know a guy in the states who has done it in a sedan. But in aus i think youd be one of the first if not the first. I rekon a supercharged V8 with the whine would sound tits.
F**k what people say. Its your car, your choice.
Good on ya man!!
