k-member alignment off - GT control arm on passenger side?

[Sp3edD3m0n]

My car was wrecked and repaired by a previous owner. I noticed that my passenger tire sits further back in the wheel well than the drivers side. So I am trying to align the k-member using the method outlined on maximum motorsports k-memmber install instructions, however I am having issues. The difference from the passenger side and driver side is 1.5 inches when measured from a point on the control arm, however less than a quarter inch when measured from a point on the k-member.

I also noticed that the two small holes on the lower control arm right under the spring are not the same between right and left. On the driver side one hole is slightly smaller than the other, however on the passenger side the two holes are exactly the same size. This leads me to believe that maybe the passenger control arm was replaced. I am speculating that it might be from a GT, however I wanted to confirm that the LCA for a GT are geometrically different and would cause the tire to sit further back if used.

gt control arms are different.

The A arms are dimensionally the same as long as the arm is from a certain year up to 04. At some point ford changed the arms to improve turning radius, I think it was 99 but am not sure. Check MM's website for info or call them they will set you straight.

As far as the k member being off by 1.5 inches, that's not un heard of. Ford built these cars with very large manufacturing tolerances. 1.5 inches would be on the high end of the tolerance but 1 Inch is very common so I wouldn't worry much about it Unless it really bothers you. I would square it as best you can and run it because you won't get it perfect no matter how hard you try.

Here you go. Ford revised the arms in 99. The only difference in the gt arms is the bushing material if they are pre 03 gt arms. Other then that they are dimensionally the same.

I have a set of 03 cobra a arms out of my brothers car for sale.

Here is the post.

Well if they are the same as far as geometry goes, then I dont need another set then. The main reason it bothered me was because I am running 295/35/17 hoosier a6 up front and it started rubbing on my fender well liner and it is very noticeable with those tire. I have been able to get it within a 1/2 inch now.

realize any misalignment on the k-member gets multiplied the further out on the LCA you go (where you measure at the k-member is at the apex of the triangle, though the angular mislaignment remains constant, the distance it represents is greater the further from the k-member you get)... if i recall the MM k-member procedure talks about less than 1/8" delta... so when you say 1/4" off, are you trying to square the k-member with the rear or are you doing the side to side measurements (diagonal)?
