heres the story, i have an s5 engine and s4 5spd tranny so i went out and got a used s5 5 spd flywheel, my problem is that the flywheel i got looks nothing like the auto flywheel on the engine and i have not yet taken out the s4 engine/tranny to compare and i want to make sure i have the correct flywheel b4 i spend money to get it machined, so foes anyone have a pic or can tell me a sure fire way to tell the difference between an s4 and s5 flywheel i appreciate it thank you.

Just checking.
This is an S5 NA with an automatic counterweight & flex plate?
You are mounting an S5 flywheel for a manual tranny swap, using an S4 tranny & drive shaft.?

If so, it should bolt up after you pull off the counterweight.
The S4/S5 clutch disc spline may be different.

BTW don't loose that counterweight.
It's a popular item since the aftermarket light flywheels need it.

the manual trans flywheel WILL look different then the auto FLEX PLATE (not a flywheel)

theres a pretty big difference between a flywheel and automatic flexplate...

An S5 N/A flywheel will have "350" stamped on the back of it. That's the surest way of identifying it.

Since you have an automatic counterweight at your disposal - it would be a PERFECT time to upgrade to a lightweight flywheel. This is a fun mod.

yes the flexplate gets replaced by the flywheel


flexplate aka automatic flywheel
flywheel aka manual trans flywheel

its all teminology.. but yes u remove that crap shoot and put the m/t one on
