I wouldn't worry though. my lower arms are 35mm longer than stock s13

You are correct sir, I was thinking about it the wrong way and it doesn't change scrub radius. I've edited my post to say such.

Because the struts have almost no camber gain these cars need a ton of static negative camber in front (~3 degrees). So even that shouldn't be a problem with adjustable camber plates.
Really the only negatives I can see is a possible loss of caster if you don't have enough adjustment in your tension rods, and hitting the fender if you are running some real meat on stock fenders.

The good thing is that the tension rods can stay in the same position if you extend the lower arm by cutting outside the mounting points and adding more LCA in there.
Thank you for the track width information. I was reading a forum with a bunch of engineers arguing about what it did and it was very general, so I didn't want to spout off information when I didn't know how it related to the s-chassis. It makes sense though considering the track width is basically equal front and rear on an S13.
