exedy Clutch oem vs stage 2, torque ratings, please help!

[ultimateirving]

So i been shopping/searching around for a clutch and the concensus has been that exedy is the best for the money. What i noticed is that i was not able to find solid information reguarding torque ratings, so website stated good up to 290/ft lb of torque, while others said up to "400whp" i know clutches should be rated by torque so can anyone confirm that 290 is the limit of stage 2?

Second question is that I found that an exedy oem replacement was rated at 280/ft lbs, if thats true it is much cheaper of a clutch and can handle about the same power.. with that logic, would this ebay kit be acceptable since it includes a lightened flywheel?

Thanks ahead of the time for help
