Greg,
Front springs vs rear springs actually will have different tensions/characteristics due to the different number of coils on the springs. Not sure how your not getting ride height when using the shock collars to adjust them. Never tried rears on fronts and vice versa.
With the other question, regardless if you tigthen the piston nut or not,you will get the same result - the piston need to travels up and down.
