whats surprising about that?
enkei are an OEM wheel supplier, such as speedline etc. Stock evo 8 wheels are Enkei, used to be OZ, but theres no reason standard wheels on cheaper cars cant be made by them. at the end of the day, they simply produce ali to custom specs, it wont cost much to create a mould and if there's a production car that they need to produce alot of wheels for, its much easier for a car manufacturer to get an actual wheel manufacturer to run a load of wheels off for them.
just because theyre made by enkei doesnt make them any different to any other wheel. you'll find that alot of cars that have alloys in the uk and europe are produced by speedline, they're simply a bulk manufacturer.
