so i went to change out my clutch and flywheel on my 2004 RX-8, when i got to the flywheel i noticed it wasnt bolt on. we were able to get it off but my new one is a bolt on flywheel, is there any way to install a bolt on? like a special tool i need?

 

You'll reuse the 54mm flywheel nut that you took off.
Which flywheel did you purchase?

 

This question is so weird, I don't even know how to being to help without seeing a picture of the two flywheels.

 

I take it you are replacing a stock flywheel with an an aftermarket aluminum one? Don't they need a mounting kit such as this one from Racing Beat?

 

Counterweight

 

Ohhh... You're probably right. He didn't get the counterweight with his flywheel.

 

Winner!

 

thanks guys, i found out i just need the counterweight

 

You can go to a local salvage yard and get one off a car with a auto trans.

 

really? that would save me the 120 bucks that gripforce is trying to charge me for one

 

Yep, just use the counterweight from Automatics.
