Please see the ScienceofSpeed Clutch Comparison Guide.

design & drivability:
With an emphasis on drivability, the clutch pedal pressure is moderately light (only about 10% greater than factory). In addition, the disc design features several key attributes that produce a factory-like smooth engagement.

The ScienceofSpeed Sport 350 Clutch & Flywheel Kit is rated for 350 lb/ft at the engine. This makes the clutch ideal for supercharged and turbocharged NSXes producing up to 350 lb/ft of torque at the engine. Looking for a higher capacity clutch for your forced induction NSX? Consider the Exedy Twin Organic (up to 425 lbf/ft) or ScienceofSpeed 500 Hybrid (up to 500 lbf/ft). 

Including a light flywheel, the ScienceofSpeed Sport 350 Clutch & Flywheel reduces the rotating weight by 11 lbs compared to the 1991-96 factory clutch assembly and 19 lbs compared to the 1997-2005 factory clutch assembly.

premium quality:
The ScienceofSpeed Sport Clutch & Flywheel Kit consists of premium components manufactured in Japan by Honda's original parts supplier as well as components built in the USA. Other similar clutches from other manufactures use pressure plate and clutch discs made overseas that vary in quality and consistency. Only the most premium components are used in this clutch & flywheel kit. Each clutch and flywheel assembly is individually assembled, tested, then dynamically balanced. The pressure plate is keyed into location so that it may only be installed the correct way.

High quality does not come at a high price. The ScienceofSpeed Sport 350 Clutch & Flywheel Kit is a complete package including everything required for installation: high quality OEM release and pilot bearings, clutch disc alignment tool and NEW OEM Flywheel Bolts.
