Hi,

I have post in the german Board but they can't help me. Sorry for my English.

I have sold a Exedy Hyper Single for my Rx8 because the Stock clutch are broken. Yesterday I wanted to install the clutch but i have one problem. The stock flywheel have one screw connection in the center. The Exedy Flywheel have around of the center six screw. The stock flywheel is still installed because i didn't had the correct tool. There give some adapter to mount this Flywheel? Can someone give my information to mount?
















Edit: Are there behind of the stock flywheel the correct adapter?

 

No, you need the RX7 automatic transmission counterweight to mount an anftermarket flywheel.

Look at my flywheel install pics, its a seperate plate that the big nut screws into and has the spots for the 6 smaller bolts.

Is this piece the same for all flywhees? Why this strange form? Why isn't it round? Does it matter how to fix it?

 

Yes, its the same piece for all flywheels.

Its not round because it is balancing the weight of the rotors and another internal counterweight inside the engine.

 

it has to be a rx8 counterweight, the fc, fd, and rx8 have different weight counterweights.
Petit, has 1 for 80bux. i'm not sure who in germany you could get it from. the only flywheel i don; think you'd need a counterweight with is Unorthodox racing.
