Secondly, Yokomo's coloured BX springs are very close in rate - they have only 0.25 coil difference between them. This may be a good step for a short touring spring but on a buggy it is far too small to make any difference. A 1/4 coil is worth 2-3% on the rate at these lengths, the AE and Losi springs are at closer to 10% difference between each rate. So as suggested above you need to go right down to a blue or pink to notice any real difference.
Thirdly, the front black springs are quite a lot stiffer than the nearest rate, at 0.75 coils stiffer than the next coloured spring. And are still at best a "medium" spring, similar to an AE silver. |
Does your, or anyone else's experience, bear out the petit chart? Just wondering cos if so it could well be worth dropping below the yokomo softest spring on the rear, or harder than the hardest on the front? Say up to AE blue up front, down to AE silver/kyosho yellow at the back?
