So I am now guessing but will confirm that I have S1 uppers but have S2/3 lowers.

You said first, stick with all the same series, but your last post talks on how adjustable it can all be, so does it really matter if I am happy to shim etc?

Only advantage I see is that GF guidance to set up is for all S2/3 components hence I'll need to find my own way if it is mixed componentry.

Is there enough adjustability to get to 3- 4 degrees positive caster?

And then to get to that sort of caster range, which S1 arm is fitted to front and which to rear? That is, am I trying to move the upper ball joint forward or rearward, compared to what a S2/3 arm set would achieve?

Tenrocca's pic of the S1 arms shows fore / aft variation perfectly, the trouble is I don't know which way it needs to be on the GF chassis.

Did you change to S2/3 uppers as the 2nd pic. shows? Why?

You are running S1 upper arms? Did you stay at 6 degrees caster and how has this felt in terms of wheel turning effort at slow turning speeds?

Additionally, to my mind the offset S1 arms then also need the spacers at the top behind the upper wishbone pivot arm, as my picture shows, to achieve the same degree of camber as a S2/3 set of arms directly bolted against the chassis, as the GF manual suggests.

Is my logic right here?
