Clutch shoe springs for the Polini Speed Clutch 3G.

For Polini 3G clutches ref. 249.001 / 249.002 / 249.004

Tuned engines deliver more power at high RPM and lose power at low RPM. If the clutch springs are not replaced with stiffer ones, acceleration worsens.

Polini's set of stiffer springs makes the clutch engage later, which makes it possible to skip the low-power RPM range and noticeably improves acceleration.

It is also recommended to replace the springs when fitting a higher-performance exhaust.
