quick Question, tried searching brought up no results.

S4 and S5 Flywheels, can they be interchanged? or are they Specific?

Reason being is i need a flywheel and no one seems to have a S5 they wanna sell but a couple guys have S4's

Thanks guys

I believe so, but you will also need the correct counterweight.

yea the front counter weight is gonna be different as well as the rear counterweight.

i wouldnt interchange them... you can ruin your motor. Its too risky

No, can't interchange, the counterweight is built into the flywheel, and is matched to the rotating assembly mass, which is different on S4 vs S5 b/c the S5 rotors are lighter. Alternately, you could go aftermarket flywheel and pick up the appropriate automatic counterweight (which is a separate piece) to use with it.
