De Arching SS Springs

Simple solution.
Buy the springs you need for your application.
If you modify the arches of the Super Stock springs (they are different on both sides for a reason) you are defeating their purpose.
I happen to like the stance that my car has with them, that's why i bought them.
Sell yours and buy the ones you need to achieve your goals instead of fooling around.......
JMHO.
