Optimize your Speed Clutch 3G engagement with this three-spring assortment from Polini.

Each set — green, yellow, and blue — offers progressive stiffness to fine-tune clutch response across your RPM range.

Stiffer springs delay engagement, pushing activation to higher engine speeds for sharper, more aggressive throttle response.
