Yet again, 600 is right. I'm a tech and over the many years I've used Hunter racks, I have learned that you can very easily go into the vehicle specifications and modify them to put "EVERYTHING IN THE GREEN". Much easier than adding shims or fighting old bent or settled suspensions or having to reposition subframes.
Though, I have done quite a few of the local gvr4's in my area and on almost every vehicle I have had to torch the rear tie rods or toe adjustment eccentrics/cams. Not because of rust either. It's just old and corroded and sometimes refuse to turn or loosen up in the first place. I've been able to get most of these cars set up absolutely perfect to either factory or user defined specs.
I guess what I am saying is, it's totally doable. Make sure the shop you take it to has an experienced tech who has done atleast a couple aws alignments and understands how to do this without melting bushings or completely ruining the alignment all together. I'd suggest talking with the tech and seeing if you can watch. Call around till you talk to somebody wbo seems confident and knowledgeable. And most importantly knows what a vr4 is when you mention it!
Edit:whoops for some reason I thought I was commenting on "miguextreme's" post -CAN THE REAR WHEELS BE ALIGNED.. Got linked here and forgot by the time I submitted my comment.
