Prepared engines give more power at high RPM and lose power at low RPM. If the clutch springs are not replaced by harder ones the acceleration gets worse.
Polini's set of harder springs makes the clutch open later, which allows to skip the low power RPM range and improves the acceleration significantly.
It is also recommended to replace the springs when fitting a higher performance exhaust pipe!
