Let me first off say that I have a 1987 Rx-7 Turbo II, Manual Transmission. I realize that only S4 Automatic Rx-7's come with a removable counterweight. Correct me if I'm wrong. Thus, buying a lightened flywheel ( In this case a Act Prolite) and a Rear S4 Counterweight I will need to also buy a hardware kit to bolt on these parts? Correct? I believe that the counterweight is built into the S4 manual transmission Rx-7's so the hardware cannot be removed when needed. My question is will I need to purchase a hardware kit to install my counterweight and flywheel or do I have the hardware needed on my stock TII.

The hardware kit will be purchased from Mazdatrix. Here is the link: http://www.mazdatrix.com/flywheel.htm

Part number: 95193

Thanks,
Nick

 

The bolts that originally held the clutch to the s4 flywheel should hold the clutch onto the aftermarket flywheel.You will need 6 bolts to hold the new flywheel to the Counterweight,and If you screwed the 54 mm nut up,you should get another one of those..(if the original one is ok,then re-use it.).
