Flywheels?
 

Are the flywheels different between the s4 and the s5? I need to find a replacement flywheel and like the oem weight. Just need to find out what to look for. I have a 90. Thanks.

i think they are??, they have different balacing, because the rotors are different weights,

They are different turbo versus non-turbo.
They are different S4 versus S5.

what he said. differences between the S4 and S5 is the balancing as kompressor mentioned and differences between turbo and non turbo is the size of the flywheel
