And if you look at the stamping on the boss (an about the two o'clock position) there is a badly stamped fake JWL marking as well - trying to suggest it has a JWL approval. Plus the fact that the markings do look to be stamped and not cast - adding further stress weak-points into the wheel, great.
If it is anything that you need to stop you in a hurry - tyres, wheels, pads, rotors, fluids, etc. then it is not worth scrimping on in my book. First thing I look at when I buy a car is the tyres on it, if people want to fit Ling Longs on a BMW then they sure ain't gonna be spending money on it!
