Father-in-law just picked up a 2004 ViperS to replace his 2002 Viper that has a Rip-Saw track, clutched and a few other Hauck Parts... Will there be a big diff in power and speed between them!
Stock for stock I would think the old Viper would have a slight advantage up top due to the lower profile track. Obviously in snow the advantage goes to the Rip saw.
It really depends on how much is done to the S...they'll probably be very close.
