Butch Capps who has built 10 Unique Cars that those spec's are no good. I have the spec's. Be sure you have your ride height where you want it, tire pressure checked, and all suspension bolts good and tight before you have it alligned. Also car needs at least 250 miles on it in order to settle the suspension
Rear End:1/2 degree negative camber,
Rear Tow in 1/32" on both wheels.
Total Tow in 1/16"
Caster, no change (because of what has to be done to change rear end caster)
Front End: 1/2 degree negative camber,
Camber left side, 2 1/4 degree positive camber
right side, 2 1/2 degree positive camber
Tow in 1/16" for each wheel, 1/8" total
Make sure you have at least a 3/4 tank of fuel.
Rear Camber can be changed the hard way and or the easier way. Jag. made .020 shims that go between the axle and brake rotors, 4 bolts. This is the hard way, nearly impossible at the time of alignment. You can loosen the 4 bolts and use the alignment shims, normally 1/32" to 1/16" will do it, then tighten the bolts back. I have done both since I had a stub axle seal leaking and had to take the axle loose.
Then there are variatioins to this alignment based on personal preference, driving styles, ect.
All measurements can convert from degree's to inches and from inches to degree's
