What have you edited? I think fixing jbeam should be priority number one. Fix that, and others will help you will the small stuff.
Ok so I want to tell you its a FWD car and in the video it looks like it was RWD , and i know a lot about this car so if you need to know anything I will might know.
Hope this makes it out one day,& always backup your files, would be nice to have this in the car wreck videos!
