Are the values quoted in the ST12 also correct for radial tires ?

On my car, i have currently following adjustment:

Camber = 0,36°/ 0.37°
Caster = 0,31° / 0.26°
Toe = 0.29° / 0.28°

I use the following specs for my alignments (with radials):

Camber: 0 degree +/- .25 degree
Caster: +2 degree +/- .5 degree
Toe in: 1/8" total (my chart tells me that equates to .26 degree total - you have slightly over that per side - slightly over 1/4" total, which would be slightly over the bias ply spec of 1/8" to 1/4").

Your caster readings are too low for good stable tracking.

thank you

to adjust the caster and camber, a 3/32 Allen wrench is needed, right ?

It is a 1/4" Allen wrench (after the rear upper outer Zerk fitting is removed, and the clamp bolt loosened - don't forget to retighten).

But there are limits to how far you can adjust. On some cars, trying to just get to 1.5 degrees caster and anywhere near 0 camber can be impossible (won't know until you try).

Note that toe in must be rechecked / readjusted anytime caster / camber is changed.
