If you want to see which of these sports cars has the smoothest ride here’s one way to find out—take a big-busted hottie along and watch her chest.

The Porsche 918 Spyder and the Dodge Viper seem to be the bumpiest, judging by the chestometer (that’s what I’m calling her breasts for measurement sake).

All of the cars are amazing but if I had to choose only one, it’d be the Porsche 918 hands down. Not only because it made her boobs bounce the most, but also because of the 944 lb-ft of torque.

It is one hell of a piece of machinery (as is its passenger), but for nearly $900,000 it better be.
