so what if you drop and then use the 620 spring with a 3/4-1" poly cushion then wouldn't you be able to have the nice stiff springs and the drop

 

Brandon,

Not sure I understand your question...
Poly coil spring insulators mearly affect ride height.

When lowering the upper control arms, you can use virtually coil spring you'd like.
Some might work better than others, but the fact you lowered the upper control arms doesn't change which coil springs you can use.

 

well i wanted to use the some 620lb springs with the drop but still ahve it streetable and i didn't want to lower the car alot 1" at the max so i would use the 3/4"or 1" coil insulator to reduce the drop cause its much thicker than the standard insulator
