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 on the V10's Build Journal, I document the unboxing, installation and driving impressions with this flywheel fitted.

The installation is relatively straight forward, for a professional. I don't consider this an easy DIY.
Chat with your local mechanical to determine if any useful while you're-in-there maintenance is useful.

The TTV flywheel is designed to fit with 9x Grade 12.9 bolts in M12x1.5x35mm dimensions. I used the ARP bolt kit #: 764-1003.
