I was reading about the new upcoming Carrera 3.8S and started wondering... It is going to hold 19" wheels in those wells. Considering rotational mass and unsprung weight, are wheels getting too big? Or are they like the CS just big enough to house the massive brakes, if the vehicle's brakes really are that big? Look at upcoming vehicles; new Corvette 19" rear, the Viper and RAM RT-10, Mercs, Infiniti FX 45 with 20", etc. 18" wheels I think are probably about as big as they need to be. It (IMO) starts to take away from the overall look of the car's body, with these huge wheel wells. I sell tires and the look on people's faces when I tell them a price for their BMW 325i's 18" wheels is precious. "HOW MUCH!" I think in recent years wheels have gotten bigger and a lot of consumers haven't even considered it. Just curious about everyone's thoughts.
