Correct spring rate for QA1 coilovers

looks like coil bind to me. likely (for starters) the spring is wayyyyyy soft. Also looks like the Dilinger LCA coil over conversion???

Need more info to get into the ballpark at what spring rate you should have. What engine? and is there anything done to take ar add any weight?
Qa1 guidline.....the spring, at installed height should collapse 25%-30%....or, a 10" spring should collapse 2-1/2" to 3" once installed and all the weight on it.

good luck with the build,
Denny
