I never mentioned stock tires. You are the one saying that. I said it will do it with drag radials.
You are also comparing apples to oranges. A challenger with drag radials is very different than a viper with drag radials. With the viper you don't need any track prep for it to stick like glue. It is a light car with, very close to 50% weight distribution front/rear "axle". My viper sticks its tires like a **** on the street without a burnout or anything track prep you name it. The drag radials will benefit most people who want to really test the new viper with the traction control off because they will be going faster with the T.C. off + a pair of D.R. on the rear than with the Nannies on. That is a fact and really the only way to know what the new viper will do best for traction in stock form. It is only $600 bucks or so for a pair, so I could care less if I have to change them every 5k or 10k.
About breaking rear axles, it is not that easy to do with ACRs ( Drag raced mine repeatedly last year with no failures) because it looks like the half shafts on the 08-10 acrs are more robust than any other vipers and were designed to take care of the stickier tires that the acrs came with according to dodge.
I believe when you buy a sports car, it is all about having fun and taking the risks into consideration but also learning how to live with them without becoming paranoid.That is enjoying a car my friend.
If the rear end will break. If, If, IF..... Let it happen first, Then, the same guys as me that paid 136K for their ACRs can give Unitrax a call and have them built a bullet proof dif. for $3500 and then launching all day long at 6000rpm after.
Lastly, AWD have their problems too and they eventually brake or cause trouble with steering, transfer-case, bearings, etc... I had an AWD car and it is just not for me but I respect and admire some awd cars. Everything comes with a price and AWD systems have their ups and downs as well.
The question you gotta ask yourself at the end of each day and if/or a failure occurred with your sport's car is:
Did I have the most amount of fun driving the car the way it was supposed to so, I could go as fast as possible? if your answer is yes, than you won't care about fixing something that broke.
Drive it, use it, race it, have fun with it!!!! Drag racing, auto crossing, etc... and etc... Don't buy a sports car to baby it, that would be insane to do it
