So I just re-measured my old links from the 2002 WRX wagon, and they were 16 1/8 in long.
When I did my alignment back in post #294, I used 15.75 in. per someone on the forum. My tires were rubbing on the trailing links
I reset the rear link to the 16 1/8 in. then re-did the string method alignment.
Its amazing how fast it goes after you did it already for the first time.
Took less than an hour to re-align the rear with the new lateral link lengths.
this is my process for aligning the rears:
Set the rear lateral link to the correct length.
Set the front link to approximate toe in of 1/8 in.
check that the lateral links are level & adjust with the long upper trailing link (level is important to eliminate roll steer)
Set the camber to - 0.75 degrees
Re-check and reset if necessary - toe in to 1/8 in each side (measured at the outer tire diameter using a flat angle)
re-check the camber.
Tighten up all lock nuts
Check toe in, level between lateral links, and camber again.
Done
Now I have 3/16 to 1/4 in. clearance from tire to trailing links.
I'm happy.
