Alex ... thanks for posting that up but it is incorrect!!! Now if you swap over the "grams" and lb/" columns then maybe ... possibly. I would still prefer to measure all the different springs on the same equipment however.....
The real numbers are likely to be in the region of 3.x for the fronts and 1.x / 2.x for the rears all in lb/"
I have started measuring through all the manufactures springs and so far I can say that AE and Losi do a pretty good job of making their springs as described.
The Yokomo spring set has some very useful rates in it when compared to the Losi / AE spring sets for use on Kyosho cars as the fronts are a similar length to Kyosho springs (cutting the losi springs down to a similar length results in VERY high rates ..... put it this way a Losi Orange, cut down and reshaped to 45 mm goes from 2.8 to 3.5 lb/" approx)
I am struggling to get hold of Academy and most importantly Kyosho spring sets to measure.
Once I have some Kyosho springs measured I will post up my findings.
The problem with using Losi springs on Kyosho cars is the free lengths are so different. The Losi front springs are too long (about 5mm) which means that getting the front ride height low enough is a problem ...... the opposite is true of the rear (about 6.5mm too short).
To get around this in the short term I am using the plastic non threaded upper platforms and Losi lower platforms on the front (with clip in spacers I have in my box from something) and 5mm spacers made by trimming old Losi screw fasterned (non threaded) upper platforms between the spring and the threaded upper seat. Both look rubbish and make adjustment a faf.
I will be turn up some proper spacers to use Losi springs on the rear as with my own chassis design on the ZX5 with the SP rear arms you can't get the rear low enough (the center of mass is further forward .... significantly).
Billthemina I'm sure your not the only person who will ask that ..... The yellow is softer than the orange .... the lower the rate number the softer teh spring.
