if i wanted to get my caster in spec, i could using shims. but im not going to bother. it drives fine and a little extra caster isnt gonna hurt anything. as far as method of adjusting toe, ive got acces to a very up to date alignment rack so thats not an issue. im just talking numbers pretty much.

for the solid axle toys, i belive spec is very close to zero toe. if you were setting it with a tape measure, i would do zero. i think the ifs toys like a little more toe in. not entirely sure on how much. i used to do 1/8" total toe when i used to set it manually (with ifs).
