Inboard toe-in is set at 3 Degrees as printed on the Blocks.
You then add or remove toe-in using the outer blocks.
Looking down on the car with the front of the car facing away from you.
When you put the insert in the side of the car Left or Right you get the toe in value that you can see printed on the insert. (+ increases toe-in, - reduces toe-in).

So 3 Degrees inboard, with the L+0.5 in the Left hub and the R+.5 in the Right Hub will give you 3.5 degrees toe-in.

Castor is similar.
Kick-up is 25 degrees.
When you put the Castor Block in you get the value next to the arrow pointing forwards (i.e. from back to the front of the car). The value must be the right way up for you to get the correct castor...

So with the +5 arrow pointing to the front of the car on both sides the castor will be 25+5 =30 Degrees.
