I want to thank Viper parts of america for the great service and price on the new tires for my viper. I replaced the 11 year old pilot sports with a set of the BFG G-force KDW. After taking the viper out for a drive with the new tires the difference is night and day. I can now floor it from a roll in first gear and the tires don't spin. Better yet I don't have to worry about the car wanting to aim for the woods on a 1-2 shift. So to all the new owners, like my self. Listen to the guys on here " get new tires" . After all what good is all that power if you can't use it or control it.
