OK, so ever since i bought my car, i have been lifting by the rear Kmember. I have had the Roush Side splitters on since day one, so the pinch weld was never an option. I also see every ford dealer I have ever been to lift from that point. Im not doubting that its a bad spot after seeing all this, but Im just saying that there is nothing wrong with my alignment or any damage. Now my car is lower so getting to a suitable lifting point other than that rear part of the kmember is almost impossible even with my low pro extra long reach jack. I will try to find a new point when I lift it next, but Im always lifting it when I'm at the track adjusting shocks, changing wheels, etc. Again, I never knew this, but I don't thing its hurt it thus far, and I have had my car since march 2013
Are you lifting it where the bolts mount to the body?
