Putting lowering blocks on super stock springs will put more leverage on the springs by the axle. This will increase spring wrap on hard launches which is exactly what ss springs are designed to eliminate. Any competent spring shop should be able to de arch the spring which is better than putting lowering blocks in.
De arching is easy if you have the correct equipment. I have de arched and re arched springs in my driveway. Just take the spring pack completely apart and place each individual spring in a jig working the spring against or with the arch depending on which way you are trying to go. Be subtle with your changes. If done correctly this will flatten the spring out and you will still have the extra half leaf that is on the ss springs ring to control axle wrap. Get an old set of springs to take apart and experiment with.
