S65 Lightweight Forged Steel Flywheel.

Swipe right for info.

It's made from forged steel and the hub is coated with nitride.

Carbon forged steel is denser than aluminum, allowing machining to tighter tolerances. The nitride coating is used reduce friction and improve wear resistance on the hub.

It's much lighter than OE.

BMW'S 2008 DCT flywheel is 27.7 lbs, down to 19.6 lbs after 08-20 while the 6spd is 27.5 lbs. The TTV DCT weighs 11.6 lbs and the MT version weighs 13.2 lbs.

It's machined and balanced to OE specs.

The balancing is done in-house to ensure a trouble free function.

It's machined to OE functionalities.

No modifications to your drivetrain or starter motor are needed. It also comes with new crank bolts from TTV.

Was it worth it?

Little had been documented about lightweight flywheels on DCT - this had been a motorsport product until recently.

The allure was too great. I took the plunge.

In this Special Series, I chat about my intentions with this upgrade, detail my unboxing impressions and the update design for 2022.

I follow it up with mission critical installation notes and wrap it up with my driving & sound impressions.

Was it worth it?

Installation Notes

I’ve always been weary of lightweight flywheels and was anxious to installing this considering the labor involved.

It isn't that hard - but you need to know what you're doing.

In this entry, I document the installation and my notes along the way.

The 6spd version

The GS6-53BZ and S65 or S85 combination can get a lightened flywheel too!

The 6spd design made from the same carbon forged steel and is slighter heavier at 6.0 kg / 13.2 lbs.


"The needle is free."

It rips thru the gears up shift it’s definitely like it’s gliding. Torque is put down stronger. It’s lighting up the tires like it’s supercharged.
