I have removed the spring quite some time ago. With car running in neutral wth e brake on, I got down under there to meaure and observe what was happening when the pedal was fully depressed and all the way up. I even pulled up on the pedal, which did not move it. Then I put the spring back in and...wait for it...exactly the same action and measurement of travel. Zero difference just more or less effort. So, I am hard pressed to believe that removing the spring could cause damage. Sigh, but alas I put the Steeda spring in anyway. Just feels like the pedal l travel is more linear and clutch disengagement point more easily felt through the pedal. Just my 2 cents.
