Alright guys... As the title really. I need to know how much an 18 inch 7 spoke OEM S3 alloy wheel weighs. Basically i've got a mate with an S3 and he's looking at aftermarket wheels but doesn't want to add any weight to the car. He'll be taking them off his car and i'll be buying them so i'm trying to hurry him into picking some! Anyway, i was hoping one of you wise men would have the answer! Thanks in advance. Appreciated as usual Paul. EDIT: Forgot to mention, the weight is to include the standard Continental Sport Contact 2 tyres!
