Fidanza's level one clutch, identified as 2.1, is comparable to most stage two clutches on the market.

The first two levels - 2.1 and 3.2 - combine uprated performance with comfortable use and provide ample power handling capacity. The 4.3 level is where you will find the highest power capacity. It is still useable on the street with minimal to no chatter. It is perfect for high bhp applications or STI's that are frequently used on track days. The last level is the 5.4 Sintered Iron clutch with a solid hub which engages like an on/off switch and is suitable for purpose built competition cars only.
