These are the highest horsepower cars EVER BUILT WORLDWIDE for less than $500,000 w/out traction and/or stability control. Viper is the perfect name for these cars, b/c they can be unpredictable to the somewhat novice driver and they can strike (spin, fishtail, etc) totally w/out warning....w/ devastating results.
But actually the cars do give you warning. It simply takes many hours in the seat to pick up these warnings. Your car will behave differently under different circumstance. I can literally feel the slightest reduction in grip in just about any situation. But I drive my car every single sunny day when I have time, and I drive her rather spiritedly. There are situations I got myself into during the first year I owned her that I never get into now...cuz just like my wife, I can tell when she is "moody" (cold tires, cold road, cold-much-higher-hp engine) which will change her handling characteristics. Up here in CT I have had my tires break loose in 3rd gear at over 80 mph....very unnerving.
No traction control or stability control is needed. Owners simply need to understand that these are street legal race cars, and they behave very much that way.
