The Maxi Speed 2G clutch from Polini comes with a reinforced base plate and low-slip clutch plates. The genius idea of the clutch spring preload adjustability makes this clutch really unique, because springs no longer break due to being pressure activated rather than pull. Admittedly not a low cost clutch, but it is the latest development from Polini and certainly for high end engines.
