The F-1 rear Camber bars are welded off center so you can put them in with the arm lower from the sway bar. The swap is straight forward, remover the old one and use it to set the length of the F-1, before you put it on number the adjuster bar 1-6 so after it is on you can move (twist) it to spread the top out and move the camber toward positive. Since I had just had the K-Mac’s put on I knew my rear camber was negative on both sides. So what I did was looking at my numbers changed each one number toward positive. Still have not been over to check them at Firestone shop but the bar does clear my lowered 1” cars sway bar.
