TTV's S54 Supalite Flywheel

[jbfrancis3]

This is a seasoned bunch. By that I mean when I went asking about SMF options, many had tried them or knew of collective experiences. Felt like a net negative outlook on here so 10 units seem like a steep hill. Folks use the terms chatter and transmission rattle interchangeably but many loath the gear lash noise inside the E46's Getrag 420g. It is indeed a noisy transmission when coupled with a SMF, worsening the lighter the flywheel gets.

How bad is the chatter?

It's not that bad - but there is some, there's no way around that with single mass.

Interest if no chatter.

TTV's S54 Supalite Flywheel : Forged Carbon

I'm thinking this may be of interest for some of you.

In the Fall of 2020, I organized a 20 set group buy for the E9X M3 TTV lightweight flywheel. It filled out rapidly. I run their DCT product.
Ben @ TTV was impressed by the rapid support of the community. I have since been working with Ben to expand the product line to all other BMW M chassis in North America, Asia, Australia and the Middle East.

This is their S54 Supalite flywheel. It weights 5.3 kg. The stock unit is 10.9kg. Great efficiency gains. These usually retail for 799 US, but I've been working Ben via the Connex for us at 600 US shipped. Could even be lower with 10x units.

From my quick research into S54 flywheels, it seems there are many aluminum alternatives.

What is you guys view on these?
