Wow, sorry! Just thought someone might be able to help me with a factory spec...it's not in the service manual, not trying to talk with fancy words...if you think for a second the rear wheels are following the front wheels your wrong. The factory wheels are mounted in rubber and move all over the place when you give the car throttle. And yes, the drag spin out was from not having enough negative preload, the car went left at the hit of the tires..low horsepower cars want to go right..high power goes left...If you want to find out if I am right..simply pull a string on the across the left rear tire of your Viper..tape it to 9 O' clock when looking at the wheel...walk to the front of the car and move the string inward to touch at 3 o'clock on the rear tire...your get an education on thrust angle. And yes, I re-sectioned the frame of the car..that's why the thrust angle needs to be checked and unfortunately, I don't have alignment heads..I was simply going to draw some lines on the floor use some basic trigonometry to calculate. My buddy Mike was nice enough to loan me a couple shocks so I could check things before welding in a cage, the front shocks were destroyed in the crash. Once the cage is in place, it would sorta be hard to move the frame around. Sorry for stirring up all the confusion! I am sure I will figure it out.....I can copy cat the 2010 from my 08.
I should have lifted in that Video..my wife wanted me to be the #1 quailfier...I leaned on it pretty hard..was lucky!
