The SMG3 OE+ lightweight flywheel is designed to fit with 9x Grade 12.9 bolts in M12x1.5x35mm dimensions. I recommend the ARP bolt kit #: 664-1003

The anxiety, and reality.

On most M cars, lightweight flywheels are a controversial modification subjective to noise & daily drivability tolerances.

I was anxious to fit this to my S85 SMG3. It is, after all, just a manual transmission with an hydraulic pump!

Not exactly.

In this Special Series, I document the unboxing, installation and driving impressions with this flywheel fitted.
