The aftermaket wheel is largely targeted to the customer who wishes to personalize his vehicle. Functionality is usually a secondary consideration, and often times sacrificed. Clearly, chosing a wheel with less backspace will give the vehicle a wider stance, which would add some positive functionality. Another functionality opportunity would be to go with a lighter wheel than stock. I would not be in the market for a heavier wheel than the stock one. In fact, I'd be looking to save at least 4 to 5 pounds a wheel. Can you list the wheel weights for each of the offers? Thank you.
