I am somewhat new to the site and I just purchased my first Viper , a 2001 GTS with some bolt-ons ( Borla, K&N, smooth tubes, etc).
I also just sold my 427 S/C Cobra that was stroked to a 462ci @ 583 hp. Needless to say, at 2300 lbs and 335's on the rear (adjustable IRS Supension) this was car is extremely quick and quite a handful to drive. I have pretty much raced most every type of car around (from 5.0's , Vipers, Ferrari,Vettes, and even the Hondas) and always came out ahead...at least to 100 mph.
I plan on getting my GTS up to that same level of performance....which includes suspension work to handle it..
