We also had 2 redemptions, both had one of each rf setup.
On the hollow square tube, there where 4 settings, on the other (capped off tube) there were only three....just something to consider.
As far as front track width, we always ran them as close IN as possible for blue/pink maxxis or burris, and as far Out as possible with maxxis ELs.
Camber was usually LF: + 1/2 RF -3.25 (but we have had success with -2.50)
I personally preferred -2.50 because it was less likely to have a push at turn in.
As far as caster we ran one kart at the factory setting ( L-blocks in center of arrows) 10° Lf & 12° rf
And the other kart for really fast or a really good biting track we would change to 8° or 9° Lf and 12° rf.
With that much caster split it can seem a little "twitchy" but had awesome corner off speed.
There is also some speed found by moving the rf L-block back 1/8 to 1/4 in.
Giving the front end a little lead.
Hope this helps!
