Was having some trouble tuning my SP 108 HP, tuned it best I could, it wasn’t bad but still breathing off it didn’t seem great. It was suggested maybe I have a weak spring and to try shimming it up to increase spring force. I didn’t have any washers that would fit over the poppet stem. So I changed the spring (216) but no difference in tuning. I had a 218 spring so I tried it... Shazam tuned up perfectly. Wasn’t sure what the differences were between the 216 and 218 spring.
Looked online and found the off-road RC car world test and compare their suspension springs to get equal force at each wheel, and they seemed to be similar in size.
After testing the two springs I found the 218 required an increase of 3/4 lbs to compress 1/2 inch compared to the 216.
Does anyone have the specs or know the supposed differences between the two spring are?
Here’s the setup, Dremel tool press and a cheep kitchen scale.
