S85 SMG3 Lightweight Forged Steel Flywheel
Swipe right for info.
Remove 12.8 lbs at the crank
The single mass design reduces rotational inertia at the crank, transforming the low to mid range response of the S85.
Forged Carbon Steel.
This material is used by TTV Racing for its higher density than aluminum, thus higher durability.
High speed balanced.
The flywheel is balanced in-house at TTV to ensure a trouble free function.
Designed for OE clutches.
The flywheel matches with the high quality OE Sachs dual-disc clutch along with the original SMG3 software.

New bolts are required
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.

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

Installation Notes
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.
Driving Impressions
The entry "It's science bro!" covers my first impression and long term review over 9 months and 15,000KM with the flywheel and carbon driveshaft combination. I discern the benefits between both and set the expectations right.
