B series flywheels

[dragonfly2k3]

Are all b-series hydro 5sp flywheels the same? If not, which all are interchangeable with a b16?(trying to get my clutch changed in one night haha)

i was under the impression they were all the same

To my knowlege they are the same, the only difference is in the pressure plate. The b16's has six bolts and the b18's have nine. I may be wrong but that is what I am thinking. I was told that the gsr flywheel is a little bit lighter but that is just hearsay.

ok, in my research in have concluded that they are all the same, the b16/b18 series range from 17-19lbs and the b18c5 is somewhere around 15. I have decided however to go 11.
