" Before you invest in a new set of coil springs to lower the front of your car, you may want to consider cutting them instead. According to chassis expert Herb Adams, cutting your (Camaro's) springs by ½ a coil will lower your car but still maintain adequate ride hieght.
1. Carfull remove the coil springs following the procedure outlined in you car's shiop manual. Note how the end coils of the spring are bent slightly so that it seats properly an the frame and A-arm. Most stock springs can be trimmed a half coil to provide the proper ride height for improved handling. Mark the spring directly across from the original end (as shown).
2. Cut the spring with an acetylene torch
3. Heat the half coil below your cut to match the spring's oiginal shape.
4. Quickly turn the spring upside down and bend the top coil by pushing down on the spring. {b]Do Not[/b] quench the spring with water; allow it to ait-cool slowly.
5. Paint and install it according to the direction on your shop manual. Realign the fron t end following the recommendation in VSE's Performance Handbook. " - Camaro Performance Handbook
I wouldn't recommend doing this to IROC springs or WS6 spring because doing this will increase the spring rate making the already rock hard performance springs even worse.
