been searching some, but still can't decide if it is possible to put s5 N/a rotors in my S4 so ill have the higher compression ratio rotors from the S5

possible?

thanks
Dennis

 

yes, you need the counter wieghts, eshaft and flywheel as well as the rotors...

been covered many times in the past

 

thats what i was looking for, thanx man

 

You dont need the eshaft for S5 rotors. Only the front counterweight and the s5 flywheel IF you dont have an aftermarket flywheel.

If you do have or plan on getting an aftermarket flywheel then you need counterweights from an Auto S5 since the rear counterweight is not part of the flywheel.
