This counter-pressure spring from Polini reduces the pressure by 30% compared to the original spring and is therefore ideal for light tuning.
The counter-pressure spring has the task of pressing the pulley in the rear converter onto the V-belt. On the other hand, it provides the counter pressure for “interconnecting” the variator.
A lighter counter-pressure spring is necessary as soon as the performance has been changed through a tuning measure so that the engine does not slip into too high a speed range. The counter-pressure spring is always closely related to the variator. If another spring is installed, the Vario must also be adjusted.
