has anyone heard anything about this? I read it in Forbes.com review of the Vibe. I'm thinking its just rumor or speculation. The article/review is fairly old (Jan 21, 2002).
http://www.forbes.com/2002/01/21/0121feat.html"In corners the Vibe GT is almost identical to the base car and, although the lower wider rubber gains a bit of cornering agility, stiffer springs and shocks--even lower wider tires, and perhaps beefier sway bars--would make the GT really scream around bends. Think we're dreaming? Pontiac's already made noise about a higher-performance version of the GT, perhaps to arrive next fall as a 2003 model."
