What is the purpose of the springs in the clutch disc???

Right. They "absorb" some of the rotational pressure of the clutch when engaging. If you drop the clutch they springs on the disc will compess completely. If you let out the clutch slowly, the springs will hardly compress at all. Basically it makes it a lot smoother as mentioned. Race clutches often don't have the springs. I believe the SPEC 5 doesnt have them.
