Dodge has just unveiled its new Avenger R/T at this year's New York Auto Show. In order to properly separate it from the standard and extremely unexciting model, engineers began by increase the roll stiffness by some 18 percent. This was accomplished by increasing the front spring rates by 17 percent and damper rates by 15 percent. Rear springs were also stiffened by 12 percent. A larger rear stabilizer bar was also added.
