You only remove the spring when you put the newer style clutch which is the diaphragm vs the old lever clutch style. I had a diaphragm clutch with the over head spring still on and the pedal would not come back up once i removed the overhead spring it was like butttter. Diaphragm clutches give the modern car feel, i personal like the old school lever style keeps my left leg in shape. Its easy to take off if you use right pry bar, not a tire iron etc. I took it off in less than 5 mins, but the first time it took forever cause i used a tire iron.
