Where did you find those figures rcz? My understanding is slightly different...
Yokomo springs are graded thus... First two figures are spring wire diameter, latter figures are number of coils - so YS-1460 is a 1.4mm, 6 coil spring.
Thicker wire = stiffer spring
Fewer coils = stiffer spring
So the order "should" be (in the YS-14 range) White, Yellow, Pink, Green, Stainless, Orange (this is the order Yokomo rate them, except the stainless which isn't listed in the chart you get with a pair of springs). Because of variances in manufacture, you can end up with values like those above if you measure springs individually though.
I believe Yokomo rate the 1355 Blue as stiffer than the 1465 White, but softer than the others. Not sure where they rate the 1560 GT4 spring.
Usable TC3 springs:
Associated TC3 Green 12.00
Associated TC3 Silver 14.50 Same as Rayspeed Silver
Associated TC3 Blue 17.00 Same as Rayspeed Blue
Associated TC3 Gold 19.50
For those that didn't know, the TC3 springs are a narrower diameter (will they rub the threaded bodies?), and use differently dimensioned shock bottoms.
Anti Roll Bar chart:
Colour Torsion Rate (N/rad) Equivalent rate at wishbone(lbs/inch)
Black 24.57 9.1
Silver 30.57 11.4
Brass 38.34 14.2
Copper 40.77 15.1
Wondering where you found these figures as well? I thought there was only three grades of Yokomo anti-roll bar, black (1mm), silver (1.2mm), gold (1.4mm).
