Hi Lanner,
Camber I can set both on the eccentric strut bolts (Golf/Rabbit I strut) and on the original lower reaction arms of my 03. Plenty of adjustment range.
Caster adjustment however is not even possible at all right now, so personally I would rather rotate those top strut plate for 90 degrees and have caster adjustment for better straightline stability at speed.
While you're at it...
Tnx,
Walter
