you dont need to replace unless it is slipping.

 

You can tell there bad when the engagement is really high, no matter how you adjust it, and the gear box will sometimes get notchy.

 

^^ yeah, mine isnt slipping yet (at WOTs) but it grabs pretty high. but not needed to change until it starts to slip.

 

My first one that lasted 65k miles was a 6 puck. It was grabbing fine but would sometimes have some clutch chatter if I didn't take off correctly. But at that point the clutch wore down to the rivets and my TOB went bad before the clutch actually started to slip. So I def could've gotten more miles from it(not sure how bad it is to use a clutch when it's worn to the rivets) if my tob didn't fall apart.

 

For daily driving the ACT will do perfectly fine but when racing and banging through gears and in the long run the Exedy Twin is the way to go.

 

thanks fellas this made a interesting read. In 2020, are the views about these clutches the same?

 

Is the Flywheel at the exedy twin lighter than the stock Flywheel?

 

Exedy twin flywheel is 11.8lbs. OEM is 13.9lbs.

After running an ACT and Exedy twin I would take the twin no question. The ACT did last forever but the high RPM lockout was insanely annoying. Never had any issues with the twin and I've had no issues now with my triple (I actually like the triple better than the twin).

 

ACT now has a the twin disc for Evo 8/9(released 11/17/2020).

Part number for act twin that is rated for 800tq(crank) T2S-M01
