Mine has the performance handling option, and the little bit I have driven it, it feels great!!
The rear ratio is 2:73... a guy gave me a link to Moser and some extra thick 3:73's that would work with the carrier... I think if I ever did anything to mod the car, the gears would be it... If I keep the car, I could buy a few go fast goodies for it after I sell my vette in the spring... Of course , I wouldnt hop it up and let my daughter drive it. If it does go to her, it will stay stock.
