Can someone explain the different stages of clutches? You know, stage 1, stage 2, stage 3, stage 4, etc.

I searched but couldn't find anything conclusive.

From what I've heard the higher in stages you go that means you have a high horsepower engine. For like a turbo civic more than stage 2 is overkill. And i think the higher you go the stiffer the clutch gets. Again im not to sure on this

the higher the stage the more strain the clutch can take. so like VTEC said, if you have a high HP motor, you need a stronger clutch to be able to transfer the power to the driveshaft/wheels.

different stages are also made from different materials. so a lower stage might not need to be made of kevlar. but a higher stage might have to be to be light but strong. even higher you get into ceramics, etc.
so heres an example from clutch masters:
FX100 series
This assembly is designed to provide extended life and superior holding power for cars with moderate power upgrades and/or more enthusiastic driving in abusive conditions. The pressure plate offers 40-65% more clamping force than a stock cover. Most organic discs provided in our assemblies include steel-backed lining to enhance the structural integrity of the material which is complemented by the highest quality hub assemblies available to ensure durability and driveability.

fx200
This clutch offers comparable torque capacity as Stage 1, but provides exceptionally smooth engagement & extended life. This is due to the full-face kevlar disc. This clutch is designed for the daily driver that desires smooth & effortless transitions. Kevlar clutch kits require a break-in period of 500-750 miles under normal driving conditions.

fx300
The perfect clutch for aggressive drivers that still desire smooth engagement. Our Stage 3 clutches utilize a segmented kevlar disc. This will provide more holding power than Stage 1 & 2, yet it still offers exceptionally smooth driveability and long life. Combined with our aluminum flywheel, this is an excellent performance upgrade.

fx400
The clutch for aggressive drivers. This is the perfect road-racing application. Stage 4 utilizes a 4-puck ceramic sprung disc complemented by a bulletproof hub assembly. It is designed for cars with significant power upgrades. Engagement is hard and quick.

fx500
This is considered a race-only application. This clutch is not designed for daily-driving. Stage 5 offers a rigid 3 or 4 puck disc without springs. Engagement is immediate. Please be advised that life expectancy is reduced when using race clutches. Please contact Clutch Masters for proper diagnosis prior to the purchase of race-only clutch kits. We commonly find that this clutch assembly is used in street driven applications where large amounts of NOS is being used where budget is an issue.

any questions?
