S65 DCT Lightweight Forged Steel Flywheel.

Swipe right for info.

It's a 2 piece design.

The hub is machined separately to be individually nitride coated for reduced friction and improved durability.

It's 8 lbs lighter than stock - or 16.1 lbs if you have an 08.

BMW'S 2008 DCT flywheel is 27.7 lbs, down to 19.6 lbs after 08-20. The TTV DCT weighs 11.6 lbs.

It's made from carbon steel.

Carbon forged steel is denser than aluminum, allowing machining to tighter tolerances.

It's machined and balanced to OE specs.

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

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.

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.

Unboxing Notes

In this entry, I examine the old, and the new: I compare the original design to the new 2022 + 2 piece design of the DCT flywheel. The MT 6spd version remains unchanged.

"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.
