yes yes we all know that heavier wheels slow down your car. But he asked for what looks good. In addition, the stock 14" wheels weigh about 15.5 lbs (93 gsr rims) and my wheels are 16" and weigh 17.5 lbs each. That's not a whole lot. Certainly not 7-12 lbs difference. There are also many wheels that are bigger than stock and weigh less. If you want to race your car get 15" lightweight wheels and sticky tires but most people just want something that looks good.
