I tried spring removal first. Worked for normal driving and occasional wot on the highway with regular tires. With drag radials, no such luck. Spoke with ford, the service writer actually gave me JPC racing's number and advised I change to the SS clutch line. Changed that the following day, but while I was at JPC (local shop for me), I asked if this was a fix and the response I got was basically NO! Asked what the problem is, Figuring since they specialize in mustang performance, they said chances are I have a bad pressure plate. I have noticed the more problems I have with the sticky clutch, the harder the pedal feels while normally driving. So it looks like a clutch will be on order for me. Just thought I would add to the conversation.
