Wow, I just bought a 2000 GTS ACR with a Paxton supercharger, Nitrous and a few other tricks (Red/silver).
Too many cars? I have 26 (I think). I much prefer my 720+rwhp Twin Screw Roe Supercharged 2001 GTS over the Paxton, but ... coming from a Ford,
The Paxton (as stated) drives pretty much stock under 3500rpm. Mine is set up for only 600rwhp on the Paxton and truly serious power comes from a Nitrous kit that puts out huge torque (insane toque off idle) and dynos 802rwhp.
You made the right choice of hardtop over ragtop if you plan to go to a track. Your coupe can legally go 11.5 ET before you get kicked off the track for going to fast. The rags need a 6 point roll bar to go faster than 13s. Also not allowed to race much on road courses and rallies with a "open cockpit".
Be careful. I have a lcoal guy that just switched to Porsche "because it's slower and easier to control" after writing off his second Gen 3 convertible.
Vipers are so well built that they protect their owners with their Death. Cliff rolled his convertible 3 times over a 20' embankment and only tore up the shoulders of his leather jacket. He said he's happy it was a Viper and he didn't die because the car was that well built. But although a 'die hard' Viper guy ... he drives a Porsche now.
Congrats on getting one of the rare coupes!
