Another feature is noticeably increased clutch life due to the addition of Brock's Performannce engineered clutch springs designed specifically for this application.
In big-displacement/high torque applications, the results are multiplied even greater. The modified-engine Busa owner has been frustrated in the past due to the unpredictable action of the clutch when additional power is applied. Billet-this-and-that help some, but they are only band aid cures.
The problem is in the clutch design, it is a mechanical problem....the BDE Hayabusa Clutch Cushion Kit is a mechanical cure.
