Reading the new tesla model s pages I found a strange reference. On the features page in the performance option section: "Performance Plus Package Performance Plus upgrades an already impressive handling car by stiffening key suspension linkages and tuning dampers to increase lateral stiffness without compromising ride. 21" wheels with wider rear rims and Michelin Pilot Sport SP2 tires channel these improvements to the road. The result is nothing short of amazing-light, responsive steering with minimal body roll. It's a performance junkie's perfect daily driver." It states : 21" wheels with wider rear rims..... I checked my car and the front ant rear are the same. Are they changing this or is this a typo?
