I hope this site can help me out here. I have the Z-car ZMXB-8 buggy that I have converted to electric. I need to find some different springs to dial it in.

So... can some of you guys post the dimensions of your springs?

I know the rate is tough to get, but once I find a few that fit, I can try measuring rates to get a range. But if you have a good dial indicator, the wire size and number of coils will help get an idea what is stiffer or softer. My rate seems close, but they just sit too low with the added weight, I am using every shim that came in the kit to get it to bones just under level.

Spring top end diameter .71 inch, about 18 mm
Spring bottom end dia. .63 inch or 16 mm

front spring
length 2.95 inch 75 mm
wire dia 0.059 inch 1.5 mm
turns 10.5 including the flattened end ones, about 7.5 active
approx rate 47.5 oz/inch

rear spring
length 3.74 inch 95 mm
wire dia 0.056 inch 1.4 mm
turns 12.7 including the flattened end ones, about 10 active
approx rate 33.5 oz/inch

The rates seem pretty good, but the ride is just too low.
