S54 harmonic damper thoughts

[BeardedRyno828]

I'm gearing up for an S54 swap here myself, and just ordered the ATI damper last week. I am running a single mass M5 clutch kit.

Single mass steel without question. There is no driveablity drawbacks only possible gains due to lower inertia.
You might experience some increased gear box rattle when warm at idle but you asking about a track car.

I’m preparing my E36 M3 track car for a S54 swap.
I’m considering the potential benefits of a aftermarket front crank harmonic damper like ATI or Ross.
Also considering what flywheel to use, steel single mass or stock E36 dual mass.
leaning towards stock dual mass S52.

Interested to hear your thoughts opinions and experience.
