Actually Shizzrock, you're the one being condescending and contemptuous - from the get go. The 'boat anchor' metaphor was a joke that somehow really got under your skin. And I was asking you seriously if you had an science or engineering background. I guess you took that personally for some reason. As for the 32 lbs wt being made up, you need to check out the available information on line, for example,
here. Do your homework before you enter a debate unprepared with facts. It's a fact that most serious car designers, esp. looking at optimizing suspensions, wheels and tires, try to minimize unsprung weight. That seems something you are contesting - why I have no idea because it's not a controversial claim.
Would you care to place a $1000 bet that the weight difference between the stock wheel and the Advanti same size wheel is more than 5 lbs? Care to put your money where your mouth is? It would be the easiest money I made this year.
For that matter, while we're on the subject, do you even own the car (Model 3 Performance version with 20 inch wheels?)
