Are you ok? Seriously man, I don't think you've understood a single thing I've said.
If you did, you would understand that I never changed my point of view, and I think it's pretty obvious that I don't agree with pretty much anything you've posted in this thread. Just read post #9. Same thing I just said in post #44. The QA1 is a well engineered system that has more drawbacks than advantages and costs a lot of money. People will buy it because it bolts in and looks complicated, but if they can't weld they won't be able to do the chassis reinforcement needed to push their cars hard enough to know the difference between the QA1 and a good set of leaf springs with a sway bar, making it a waste of money.
